move SAL_CACHE_FLUSH check later in boot

The check to see if the firmware drops interrupts during a
SAL_CACHE_FLUSH is done to early in the boot.
SAL_CACHE_FLUSH expects
to be able to make PAL calls in virtual mode, on some cell
based
machines a fault occurs causing a MCA. This patch moves the
check
after mmu_context_init so the TLB and VHPT are properly
setup.
