Because mtk-mutex change to use unsigned long mutex module type,
it should depend 64BIT. This is a preparation for adding support for
mt8195 vdosys1 mutex.

Breaking old platforms is forbidden.

MT2701 and MT7623N are 32-bit ARM SoCs and:
- mt2701 needs mmsys only; but
- mt7623n needs mmsys and mutex.

Besides, this is an easy fix: just change your unsigned long to a fixed size u64.
