[PATCH v6 14/20] drm/mediatek: Add component ID to component match structure

Add component ID to component match structure so we can
configure them with a for-loop.

The main reason we do such code refactoring is that
there is a new hardware component called "Padding" since
MT8188, while MT8195 doesn't have this module, we can't
use the original logic to manage the components.

While MT8195 does not define Padding in the device tree,
the corresponding components will be NULL and being skipped
by the functions.
