mtk mutex is a driver used by DRM and MDP [1], so this series move
mtk mutex driver from DRM folder to soc folder, so it could be used
by DRM and MDP.
Changes in v2:
1. Rebase onto mediatek-drm-next [2].
2. Export symbol for mtk-mutex API.

In this series, why only gamma and color add pm runtime support? I
think all ddp component need pm runtime support. And pm runtime
support is not related to mt8192, so move these patches

This patch has conflicts with the series "Decouple Mediatek DRM sub
driver" [1] which has been applied to mediatek-drm-next, so please
rebase this patch onto mediatek-drm-next.

Describe why need this patch. I think the reason is:
For current mediatek dsi encoder, its possible crtc is fixed in crtc
0, and mediatek dpi encoder's possible crtc is fixed in crtc 1. In
some SoC the possible crtc is not fixed in this

tz_disabled is used to control mtk_hdmi output signal, but this variable
is stored in mtk_hdmi_phy and mtk_hdmi_phy does not use it. So move
tz_disabled to mtk_hdmi where it's used.

mtk_hdmi_phy is a part of mtk_hdmi module, but phy driver should be an
independent module rather than be part of drm module, so separate the phy
driver to an independent module.

mtk_hdmi_phy is currently placed inside mediatek drm driver, but it's
more suitable to place a phy driver into phy driver folder, so move
