In preparation of using the upstream mt7988a.dtsi when switching
to Linux 6.12 prepare by bringing our downstream version closer to
what went upstream.
* rename 'xphy' -> 'xsphy'
* rename 'uart[012]' -> 'serial[012]'
* only list pinctrl settings directly used in mt7988a.dtsi there,
leave it to boards to define all additional pinctrl settings
they need.
* move fan and thermal-zone to board level
