powerpc/85xx: Fix writing to spin table 'cpu-release-addr' on ppc64e
If the spin table is located in the linear mapping (which can happen if
we have 4G or more of memory) we need to access the spin table via a
cacheable coherent mapping like we do on ppc32 (and do explicit cache
flush).
See the following commit for the ppc32 version of this issue:
