[PATCH v6 3/5] drm/panfrost: Commonize Mediatek power domain array definitions

[Louis-Alexis Eyraud]

In the panfrost driver, the platform data of several Mediatek SoC
declares and uses several different power domains arrays according to
GPU core number present in the SoC:
- mediatek_mt8186_pm_domains (2 cores)
- mediatek_mt8183_pm_domains (3 cores)
- mediatek_mt8192_pm_domains (5 cores)

As they all are fixed arrays, starting with the same entries and the
platform data also has a power domains array length field
(num_pm_domains), they can be replaced by a single array, containing
all entries, if the num_pm_domains field of the platform data is also
set to the matching core number.

So, create a generic power domain array (mediatek_pm_domains) and use
it in the mt8183(b), mt8186, mt8188 and mt8192 platform data instead.
