Add support for the PolarFire SoC system controller

From: Conor Dooley <[email protected]>

This patch series adds support for the system controller on the PolarFire SoC, using the mailbox framework. A Microchip directory in the SoC subsystem has been created to hold the mailbox client driver and will be used for future service drivers.

This directory is included by the kconfig option:
CONFIG_SOC_MICROCHIP_POLARFIRE, so this patch series depends on Atish Patra's PolarFire SoC support patches which introduce that option.

Changes from v1:
* Squashed header into first patch
* Fixed DT binding warnings & small fixes
* Cleaned up drivers from feedback

Conor Dooley (5):
mbox: add polarfire soc system controller mailbox
dt-bindings: add bindings for polarfire soc mailbox
soc: add polarfire soc system controller
dt-bindings: add bindings for polarfire soc system controller
