Samsung pinctrl DTS and driver changes for v5.18
Conversion of Samsung pinctrl bindings to dtschema followed up with
alignment of DTS files to the dtschema.
The entire work consists of three parts but everything should be merged
at once to avoid dtschema check errors:
1. Samsung pinctrl driver change necessary to accept new DTS (driver
depends on node names and this has to be adjusted because of dtschema).
2. Conversion to dtschema which brings requirement of different naming
of the GPIO nodes.
3. DTS commits depending on driver (1) above, which convert all GPIO pin
bank names to new naming, required by dtschema.
This also includes few cleanups around DTS which are here to avoid
any merge conflicts.
The Samsung pinctrl driver changes are backwards compatible. However
the DTS changes (renaming nodes) could cause problems in out-of-tree or
other project implementations of the driver.

Add dummy/fake voltage regulators for USB DWC3 block on Exynos5410
SMDK5410 board. These regulators are required by dtschema, however the
SMDK5410 board does not define the PMIC providing regulators. Use dummy
fixed-regulators just to satisfy the dtschema checks.

The S3C RTC requires 32768 Hz clock as input which is provided by PMIC.
However the PMIC is not described in DTS at all so at least add
a workaround to model its clock with a fixed-clock. This fixes S3C RTC
and silences dtbs_check warnings like:
arch/arm/boot/dts/exynos5410-smdk5410.dt.yaml: rtc@101e0000: clocks: [[5, 317]] is too short
arch/arm/boot/dts/exynos5410-smdk5410.dt.yaml: rtc@101e0000: clock-names: ['rtc'] is too short

Fix up inconsistent usage of upper and lowercase letters in "Samsung"
and "Exynos" names.
"SAMSUNG" and "EXYNOS" are not abbreviations but regular trademarked
names. Therefore they should be written with lowercase letters starting
with capital letter.
The lowercase "Exynos" name is promoted by its manufacturer Samsung
Electronics Co., Ltd., in advertisement materials and on website.
Although advertisement materials usually use uppercase "SAMSUNG", the
lowercase version is used in all legal aspects (e.g. on Wikipedia and in
privacy/legal statements on
https://www.samsung.com/semiconductor/privacy-global/).

Pull "Topic branch for Samsung DeviceTree cleanup for 4.9" from Krzysztof Kozłowski:
Replace in DT sources hard-coded values for pinctrl configuration like pull
up/down, drive strength and function. This makes the DTS easier to read,
especially that some drive strengths values are quite non-obvious.

Usage of DTS macros instead of hard-coded numbers makes code easier to
read. One does not have to remember which value means pull-up/down or
specific driver strength.

The skeleton.dtsi file was removed in ARM64 for different reasons as
explained in commit ("3ebee5a2e141 arm64: dts: kill skeleton.dtsi").
These also applies to ARM and it will also allow to get rid of the
following DTC warnings in the future:
"Node /memory has a reg or ranges property, but no unit name"
The disassembled DTB are almost the same besides an empty chosen
node being removed and nodes reordered, so it should not have
functional changes.

The exynos5.dtsi is used for common nodes shared between Exynos5250 and
Exynos542x. Since Exynos5410 is very similar to Exynos5420 it can
include the common file as well to remove duplication and make
everything more consistent.

dw-mmc in exynos
dw-mmc controller can support multiple slots.
But, there are no use-cases anywhere. So we don't need to support the
slot-node for dw-mmc controller.
And "supports-highspeed" property in dw-mmc is deprecated.
"supports-highspeed" property can be replaced with "cap-sd/mmc-highspeed".
