xen/arm: p2m: Introduce p2m_tlb_flush_sync, export it and use it

Multiple places in the code requires to flush the TLBs only when
p2m->need_flush is set.

Rather than open-coding it, introduce a new helper p2m_tlb_flush_sync to
do it.

Note that p2m_tlb_flush_sync is exported as it might be used by other
part of Xen.
