sparc32: implement proper LEON support in head_32 (after highmem)
sparc32: implement proper LEON support in head_32 (after highmem)

We use the compatibility property to determine the
sun models. For leon we use psr.impl and ignore the
result of the getprops call.

Include a hack to allow build as the support code
is not yet converted.
