hw/riscv: microchip_pfsoc: Hook GPIO controllers

Browse source 
Microchip PolarFire SoC integrates 3 GPIOs controllers. It seems
enough to create unimplemented devices to cover their register
spaces at this point.

With this commit, QEMU can boot to U-Boot (2nd stage bootloader)
all the way to the Linux shell login prompt, with a modified HSS
(1st stage bootloader).

For detailed instructions on how to create images for the Icicle
Kit board, please check QEMU RISC-V WiKi page at:
