fmap: Make FMAP_CACHE mandatory if it is configured in

Browse Source 
Now that we have a CONFIG_NO_FMAP_CACHE to completely configure out the
pre-RAM FMAP cache code, there's no point in allowing the region to be
optional anymore. This patch makes the section required by the linker.
If a board doesn't want to provide it, it has to select NO_FMAP_CACHE.

Adding FMAP_CACHE regions to a couple more targets that I think can use
them but I don't know anything about... please yell if one of these is
a bad idea and I should mark them NO_FMAP_CACHE instead.
