ArmPkg,UefiCpuPkg: fix boot failure with LPA2
When FEAT_LPA2 is enabled:
1. The DS bit is located at bit 32, not bit 59, when HCR_EL2.E2H = 0.
2. The root level of the page table should be -1 when
using a 52-bit address with a 4KB TxSZ and LPA2 feature is enabled.
However, the current implementation does not handle
these conditions correctly, causing EFI to fail
during boot when CPU is EL0&1 or EL0&2.
Fix this boot failure.
