soc: microchip: add mpfs gpio interrupt mux driver

On PolarFire SoC there are more GPIO interrupts than there are interrupt
lines available on the PLIC, and a runtime configurable mux is used to
decide which interrupts are assigned direct connections to the PLIC &
which are relegated to sharing a line.

Add a driver so that Linux can set the mux based on the interrupt
mapping in the devicetree.

soc: microchip: add mfd drivers for two syscon regions on PolarFire SoC

The control-scb and mss-top-sysreg regions on PolarFire SoC both fulfill
multiple purposes. The former is used for mailbox functions in addition
to the temperature & voltage sensor while the latter is used for clocks,
resets, interrupt muxing and pinctrl.

Introduce a function that allows a driver with a reference to the system
controller to get one to a flash device attached to it.
