In order to prepare addition of future SoC, split the current driver
into common shared code and SoC specific drivers:
- mtk-power-domain.c now only holds the common register access and
power on/off/request/probe logic plus the shared power_domain_ops.
- mtk-power-domain.h exposes the register definitions, the mtk_scp_domain
data structures and the core helpers to the per-SoC drivers.
- mt7623-power-domain.c and mt7629-power-domain.c each hold their own
domain table and U_BOOT_DRIVER registration. The mt7629 driver also
matches the mt7622 compatible, preserving the previous behaviour.
Update the mt7622, mt7623 and mt7629 defconfigs to select the matching
per-SoC driver.
No functional change intended.
