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: mpfs: enable access to the system controller's flash The system controller has a flash that contains images used to reprogram the FPGA using IAP (In-Application Programming). Introduce a function that allows a driver with a reference to the system controller to get one to a flash device attached to it.

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.
