mediatek: u7623: fix network switch enumeration

Browse Source 
With upstream changes hitting kernel 6.4 the dtb for u7623 ends up with
both mac (gmac) disabled, since this is now the default status in
mt7623.dtsi. Fix this by including mt7623a.dtsi (which already has all
necessary bits) and enabling all revlevant ports. This will also do
a side hustle of assigning proper clocks for power controller and
specifying proper power domain for few devices.
