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.

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.

Mediatek HDMI phy driver is moved from drivers/gpu/drm/mediatek to
drivers/phy/mediatek, so add the new folder to the Mediatek DRM drivers'
information.

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
mtk_hdmi_phy driver into phy driver folder.
