mt76: mt7921: use physical addr to unify register access

commit f1e2eef111018a4f0d280656be4351c37e9e554b upstream.

Use physical address to unify the register access and reorder the
entries in fixed_map table to accelerate the address lookup for
MT7921e. Cosmetics the patch with adding an extra space to make all
entries in the array style consistent.
