Microchip RISC-V devicetrees for 5.20

Browse Source 
A pair of changes for mpfs.dtsi:
 - A pair of patches from Suresh & I, removing the bogus max frequency
   properties from the controller nodes for {q,}spi. This is a device
   only property with no meaning for a controller and should never have
   been there.
 - RISC-V has no sensible defaults for cpu topology, so I added a this
   information to the dt for MPFS as a cpu-map. This is an optional
   property and therefore is not a fix.
