xtensa: move MPU constants from .data to .ref.rodata
MPU attribute mapping table is R/O, move it from .data to __REFCONST (as the rest of the _startup code where initialize_cacheattr is used is in the __REF section). This allows executing initialize_cacheattr before the data section of the XIP kernel is relocated to its place. Signed-off-by: Max Filippov <jcmvbkbc@gmail.com>
