power: domain: mediatek: use MT2701 naming instead of MT7623

Upstream DT bindings define "mediatek,mt7623-scpsys" to fall back to
"mediatek,mt2701-scpsys". Align the driver with this convention by
using MT2701 naming throughout.

This also allows the driver to use the upstream
dts/upstream/include/dt-bindings/power/mt2701-power.h header instead of
the local include/dt-bindings/power/mt7623-power.h, since both expose
equivalent power domain definitions.

Rename scp_domain_mt7623 to scp_domain_mt2701, replace SCPSYS_MT7623
enum by SCPSYS_MT2701, and switch all MT7623 power domain defines to
their MT2701 equivalents.

Note:
we intentionally keep the explicit "mediatek,mt7623-scpsys"
compatible entry to avoid breaking legacy boards
(mt7623a_unielec_u7623_02 and mt7623n_bpir2_defconfig) that didn't
switched yet to OF_UPSTREAM. Same for
include/dt-bindings/power/mt7623-power.h that is only used in these
boards.
