memory: brcmstb_memc: Simplify compatible matching

Now that a "brcm,brcmstb-memc-ddr-rev-b.2.x" fallback compatible string
has been defined, we can greatly simplify the matching within the driver
to only look for that compatible string and nothing else.

The fallback "brcm,brcmstb-memc-ddr" is also updated to assume the V21
register layout since that is the most common nowadays.
