arm64: mm: Wire up TCR.DS bit to PTE shareability fields
When LPA2 is enabled, bits 8 and 9 of page and block descriptors become
part of the output address instead of carrying shareability attributes
for the region in question.
So avoid setting these bits if TCR.DS == 1, which means LPA2 is enabled.
