Subject: [PATCH] dt-bindings: display: mediatek: dpi: Update device list with power-domains

There are two kinds of MediaTek DPI devices in the tree: the ones with a
power domain and those without (or missing). The former are the majority
and are more common in newer DTs. Only three older DTs fall into the
latter category: MT2701, MT7623 and MT8192.

However, the current binding only allows particular DPI devices to have
power domains, which results in spurious binding check errors against
existing and new DTs.

Instead of diligently maintaining the allowed list, let's do it the
other way around - create an exception list for devices that are fine
not specifying a power domain. This list is expected to be fixed, and it
encourages new MTK DPI devices to describe their power domain whenever
possible; if not, those should be listed with proper rationale.
