Subject: [PATCH v2 0/5] firmware: arm_scmi: add SCMI v2.0 fastchannels and reset protocol support

SCMI v2.0[1] released recently adds support for:

1. Performance protocol fast channels
2. Reset Management Protocol
among several other features.

This series adds support for the above 2.

The code is based on the cleanup[2] and Rx/async/delayed response series[3]
and is available @[4]

v1[5]->v2:
	- Changed the macro SCMI_PERF_FC_RING_DB to use do {} while(0)
	- Renamed RESET_ARM_SCMI to RESET_SCMI and reworded Kconfig text
	- Dropped unused struct device pointer from scmi_reset_data
	- Added to_scmi_handle which helped to remove some repetitive code
	- Fixed some doxygen comments
	- Initialised rcdev.nr_resets
	- Fixed MODULE_DESCRIPTION
