Add a driver to support the Polarfire SoC gpio controller.
Tested with latest 5.19 kernel.
MPFS gpio interrupts are connected to IOMUX configured by system
register GPIO_INTERRUPT_FAB_CR(31:0). Interrupt connection for
some GPIO's to the PLIC (Platform Level Interrupt Controller) can be
shared (not directly connected) or direct if connection is available.
previously upstreamed dt-bindings: gpio: microchip,mpfs-gpio.yaml
Changes in v6
Fixed typo causing compile issue with kernel 6.0-rc1
