Implement an I2C controller sharing mechanism between the host (kernel)
and PSP co-processor on some platforms equipped with AMD Cezanne SoC.
On these platforms we need to implement "software" i2c arbitration.
Default arbitration owner is PSP and kernel asks for acquire as well
as inform about release of the i2c bus via mailbox mechanism.

The solution is similar to i2c-designware-baytrail.c implementation, where
we are using a generic i2c-designware-* driver with a small "wrapper".
In contrary to baytrail semaphore implementation, beside internal
acquire_lock() and release_lock() methods we are also applying quirks to
lock_bus() and unlock_bus() global adapter methods. With this in place
all i2c clients drivers may lock i2c bus for a desired number of i2c
transactions (e.g. write-wait-read) without being aware of that such bus
is shared with another entity.
Modify i2c_dw_probe_lock_support() to select correct semaphore
implementation at runtime, since now we have more than one available.
Configure new matching ACPI ID "AMDI0019" and register
ARBITRATION_SEMAPHORE flag in order to distinguish setup with PSP
arbitration.
Add myself as a reviewer for I2C DesignWare in order to help with reviewing
and testing possible changes touching new i2c-designware-amdpsp.c module.

Pull more ACPI updates from Rafael Wysocki:
"The most significant item here is the Platform Firmware Runtime Update
and Telemetry (PFRUT) support designed to allow certain pieces of the
platform firmware to be updated on the fly, among other things.
Also important is the e820 handling change on x86 that should work
around PCI BAR allocation issues on some systems shipping since 2019.
The rest is just a handful of assorted fixes and cleanups on top of
the ACPI material merged previously.
Specifics:
- Add support for the the Platform Firmware Runtime Update and
Telemetry (PFRUT) interface based on ACPI to allow certain pieces
of the platform firmware to be updated without restarting the
system and to provide a mechanism for collecting platform firmware
telemetry data (Chen Yu, Dan Carpenter, Yang Yingliang).
- Ignore E820 reservations covering PCI host bridge windows on
sufficiently recent x86 systems to avoid issues with allocating PCI
BARs on systems where the E820 reservations cover the entire PCI
host bridge memory window returned by the _CRS object in the
system's ACPI tables (Hans de Goede).
- Fix and clean up acpi_scan_init() (Rafael Wysocki).
- Add more sanity checking to ACPI SPCR tables parsing (Mark
Langsdorf).
- Fix up ACPI APD (AMD Soc) driver initialization (Jiasheng Jiang).
- Drop unnecessary "static" from the ACPI PCC address space handling
driver added recently (kernel test robot)"

Because devres_alloc() may fail, devm_ioremap() may return NULL.
Then, 'clk_data->base' will be assigned to clkdev->data->base in
platform_device_register_data().
The PTR_ERR_OR_ZERO() check on clk_data does not cover 'base', so
it is better to add an explicit check against NULL after updating
it.

ARCH_VULCAN arm64 platform (for Broadcom Vulcan ARM64 processors) has
been discontinued. Cavium's ThunderX2 CN99XX (ARCH_THUNDER2) will be
the next revision of the platform.
Update compile dependencies and ACPI ID to reflect this change. There
is not need to retain ARCH_VULCAN since the Vulcan processor was never
in production and ARCH_VULCAN will be deleted soon.

We have a couple of drivers, acpi_apd.c and acpi_lpss.c,
that need to pass extra build-in properties to the devices
they create. Previously the drivers added those properties
to the struct device which is member of the struct
acpi_device, but that does not work. Those properties need
to be assigned to the struct device of the platform device
instead in order for them to become available to the
drivers.
To fix this, this patch changes acpi_create_platform_device
function to take struct property_entry pointer as parameter.

For structure types defined in the same file or local header files, find
top-level static structure declarations that have the following
properties:
1. Never reassigned.
2. Address never taken
3. Not passed to a top-level macro call
4. No pointer or array-typed field passed to a function or stored in a
variable.
Declare structures having all of these properties as const.
Done using Coccinelle.

The UART driver, dw8250.c, needs some details regarding the
Designware UART. For ACPI enumerated devices the values are
hard-coded, but since the driver also reads the values from
device properties, providing them with build-in properties.
This allows us to later remove the hard-coded values from
the driver.

Add device HID AMDI0020 to match the AMD ACPI Vendor ID (AMDI) as
registered in http://www.uefi.org/acpi_id_list, and the UART
controller on future AMD paltform will use the HID instead of AMD0020.

Clock provider drivers generally shouldn't include clk.h because
it's the consumer API. Remove the includes here because these are
a provider drivers.

This new feature is to interpret AMD specific ACPI device to
platform device such as I2C, UART, GPIO found on AMD CZ and
later chipsets. It based on example intel LPSS. Now, it can
support AMD I2C, UART and GPIO.
