[PATCH 0/2] arm64/mm: Drop TTBR_CNP_BIT and TTBR_ASID_MASK

[Anshuman Khandual]

Directly use existing tools sysreg format field macros TTBRx_EL1_CNP_BIT/
TTBRx_EL1_ASID_MASK, while also dropping off now redundant custom macros
TTBR_CNP_BIT and TTBR_ASID_MASK. With this change in place, there are no
more TTBR_EL1 register based custom macros left in the tree.

This was discussed and suggested earlier.

Series applies on v7.0-rc1.
