[GIT PULL] firmware: arm_scmi: updates for v5.4

[Sudeep Holla]

Hi ARM SoC Team,

Please pull !
There are minor changes in clock and hwmon subsystems that are Acked-by
Stephen Boyd and Guenter Roeck. It also contains a new reset driver that
is reviewed by Philipp Zabel. Further all these are in -next for a while.

Regards,
Sudeep

  reset: Add support for resets provided by SCMI (2019-08-12 12:23:02 +0100)

----------------------------------------------------------------
ARM SCMI updates/fixes for v5.4

Handful of fixes/updates including:
1. SCMI v2.0(recently released) support for:
	- Performance protocol fast channels
	- Reset Management Protocol
2. SCMI infrastructure/core support for recieve(Rx) channels,
   asynchronous commands and delayed response
3. Usage of asynchronous commands for clock rate setting and sensor
   reading based on the attributes read from the firmware
4. Miscellaneous cleanups(typos, naming alignment with specification,
   and SPDX License identifier)
5. Couple of fixes: removal of extra check for invalid length and
   additional check to ensure platform/firmware has released shared
   memory before using it in OSPM

----------------------------------------------------------------
