MediaTek SoCs have multiple MFG power-domains, exclusively used for
the GPU which, in turn, requires external power supplies: make sure
to have the MTK_SCPD_DOMAIN_SUPPLY cap on the two topmost MFGs to
allow voting for regulators on/off upon usage of these power domains.
This also ensures that the SRAM is actually powered and that we're
not relying on the bootloader leaving this supply on when performing
the first (and latter) poweron sequence for these domains' sram.

MT8195 has more than 32 power domains so it needs
two set of pwr_sta and pwr_sta2nd registers,
so move the register offset from soc data into power domain data.

Add the power domains names for the mt8183 SoC. This removes the debugfs
errors like the following:
debugfs: Directory 'power-domain' with parent 'pm_genpd' already present!
Fixes: eb9fa767fb ("soc: mediatek: pm-domains: Add support for mt8183")

Some power domains (eg. mfg) needs to turn on power supply before power
on.
