In preparation for adding new bindings for new MediaTek SoCs, split out
the power-domains variation from the `else` in the current
mediatek,mt8183-mali conditional.

The sram-supply part is left in place to be disallowed for anything
that is not compatible with "mediatek,mt8183-mali" as this regulator
is MediaTek-specific and it is, and will ever be, used only for this
specific string due to the addition of the mediatek-regulator-coupler
driver.

Commit ("dt-bindings: gpu: mali-bifrost: Add Mediatek MT8183")
incorrectly introduced power domain names for MT8183, causing
validation issues.

Add power-domain-names to the base schema, allowing a maximum of
five elements; since platforms having a single power domain don't
need any actual domain name, disallow that for each sub-schema.

* [PATCH v4 04/12] dt-bindings: gpu: mali-bifrost: Add sub-schema for MT8192's power domains

MediaTek MT8192 (and similar) needs five power domains for the
Mali GPU and no sram-supply: change the binding to allow so by
also introducing power-domain-names in the generic binding;
while at it, also disallow the newly introduced power-domain-names
for all non-MediaTek bindings.

MT8186 has a Mali-G52 MC2 2EE GPU (two cores): add a binding with
two power domains (one per core) for it.

MediaTek MT8192 has a Mali-G57 with a special GPU ID. Add its GPU ID,
but treat it as otherwise identical to a standard Mali-G57.

We do _not_ fix up the GPU ID here -- userspace needs to be aware of the
special GPU ID, in case we find functional differences between
MediaTek's implementation and the standard Mali-G57 down the line.

MediaTek MT8192 has a Mali-G57 with a special GPU ID. Add its GPU ID,
but treat it as otherwise identical to a standard Mali-G57.

We do _not_ fix up the GPU ID here -- userspace needs to be aware of the
special GPU ID, in case we find functional differences between
MediaTek's implementation and the standard Mali-G57 down the line.

The "mediatek,mt8183-mali" compatible uses platform data that calls for
getting (and managing) two regulators ("mali" and "sram") but devfreq
does not support this usecase, resulting in DVFS not working.

Since a lot of MediaTek SoCs need to set the voltages for the GPU SRAM
regulator in a specific relation to the GPU VCORE regulator, a MediaTek
SoC specific driver was introduced to automatically satisfy, through
coupling, these constraints: this means that there is at all no need to
manage both regulators in panfrost but to otherwise just manage the main
"mali" (-> gpu vcore) regulator instead.

Keeping in mind that we cannot break the ABI, the most sensible route
(avoiding hacks and uselessly overcomplicated code) to get a MT8183
node with one power supply was to add a new "mediatek,mt8183b-mali"
compatible, which effectively deprecates the former.

MediaTek MT8186 has a Mali-G52 MC2 2EE (Bifrost): add a new compatible
and platform data using the same supplies list as "mt8183_b" (only one
regulator), and a new pm_domains list with only two power domains.
