mediatek: mt7623 enable arch-timer with a patch

Last attempt on this has a typo and doen't work.
It seems that this is a common problem occurring on every kernel bump,
so let's enforce arch timer support for mt7623 with a patch instead.

Fixes: 9a22943 ("mediatek: 5.15: re-enable arch timer on MT7623 as well")
