On 64 bit architecture, we have plenty of vmalloc space
so that we can keep all the ptes mapped always
But on 32 but architecture, vmalloc space is limited and
hence we have to map/unmap ptes when required
Hence add new APIs for arch64 and call them if
IS_ENABLED(CONFIG_ARM64) is true

Add two fb flushes after bar1 bind. This should hang the thread instead
of whole system in case there is a BAR1 hang.
