If secure authentication of a devices fails, either because the device
already has another key uploaded, or there is some other error sending
challenge to the device, and the user only wants to approve the device
just once (without a new key being uploaded to the device) the current
implementation does not allow this because the key cannot be cleared
once set even if we allow it to be changed.
Make this scenario possible and allow clearing the key by writing
empty string to the key sysfs file.

>From what I can tell, we don't really need to treat ch_addr as

Also, we were passing a drvdata pointer to the
coresight_timeout() function, but we really wanted to pass the
address of the register base. Luckily the base is the first
member of the structure, so everything works out, but this is
quite unsafe if we ever change the structure layout. Clean this
all up so sparse stops complaining on this code.

The coresight SoC 600 supports ETR save-restore which allows us
to restore a trace session by retaining the RRP/RWP/STS.Full values
when the TMC leaves the Disabled state. However, the TMC doesn't
have a scatter-gather unit in built.
Also, TMCs have different PIDs in different configurations (ETF,
ETB & ETR), unlike the previous generation.
While the DEVID exposes some of the features/changes in the TMC,
it doesn't explicitly advertises the new save-restore feature
as described above.

The Coresight SoC 600 TMC ETR supports save-restore feature,
where the values of the RRP/RWP and STS.Full are retained
when it leaves the Disabled state. Hence, we must program the
RRP/RWP and STS.Full to a proper value. For now, set the RRP/RWP
to the base address of the buffer and clear the STS.Full register.
This can be later exploited for proper save-restore of ETR
trace contexts (e.g, perf).

TMC in Coresight SoC-600 advertises the AXI address width
in the device configuration register.
Bit 16 - AXIAW_VALID
0 - AXI Address Width not valid
1 - Valid AXI Address width in Bits[23-17]
Bits [23-17] - AXIAW. If AXIAW_VALID = b01 then
0x20 - 32bit AXI address bus
0x28 - 40bit AXI address bus
0x2c - 44bit AXI address bus
0x30 - 48bit AXI address bus
0x34 - 52bit AXI address bus
Use the address bits from the device configuration register, if
available. Otherwise, default to 40bit.

With new version of TMC ETR, there are differing set of
features supported by the TMC. Add the capability of a
given TMC ETR for making safer decisions at runtime.
The device configuration register of the TMC (DEVID) lists
some of the capabilities. So, we can detect some of them at
probe. However, some of the features (or changes in behavior)
are not advertised and we have to depend on the PID to infer
the features. So we use a static description of the "unadvertised"
capabilities attached to the PID. Combining both, the static
and the dynamic capabilities, we maintain a bitmask of the
available features which can be later checked to take
appropriate actions.

2) Changes the Kconfig symbol (since this is not part of any defconfigs)
CORESIGHT_QCOM_REPLICATOR => CORESIGHT_DYNAMIC_REPLICATOR
3) Improves the help message in the Kconfig.
