powerpc/virtex5: Fix Virtex5 machine check handling
commit 640d17d60e83401e10e66a0ab6e9e2d6350df656 upstream. The 440x5 core in the Virtex5 uses the 440A type machine check (ie, they have MCSRR0/MCSRR1). They thus need to call the appropriate fixup function to hook the right variant of the exception. Without this, all machine checks become fatal due to loss of context when entering the exception handler.
