iommu/arm-smmu: Request TZ to change page table format to V8L
For targets where we have slave side protection,
global register programming is handled by TZ. And
since it supports V7S page table format only, by
default TZ programs all context bank to permit
V7S format by programming VA64 bit of CBA2R register
as 0.
But if context bank itself is non secure then its
page tables are managed by HLOS where we can
support V8L page table format. So, provide a way
to request TZ to change page table format to V8L
for non secure context banks.
