pic64gx is not compatible with mpfs because due to the lack of FPGA
functionality some features are disabled. Notably, anything to do with
FPGA fabric contents is not supported.

The system controller "shares" a SPI flash device with a QSPI controller
in the MSS. This flash is used to store FPGA bitstreams & other
metadata. IAP and Auto Upgrade both write images to this flash that the
System Controller will use to re-program the FPGA.
Add a phandle property signifying which flash device is connected to the
system controller.

The services actually provided by the system controller are not
documented so add some words about what the system controller can
actually do. Add a link to the oneline documentation with the specific
details of each individual service.
Also, drop the unneeded label from the example.

The Polarfire SoC is currently using two different compatible string
prefixes. Fix this by changing "polarfire-soc-*" strings to "mpfs-*" in
its system controller in order to match the compatible string used in
the soc binding and device tree
