From: CK Hu
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.

From: CK Hu
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.

Mediatek HDMI phy driver is moved from drivers/gpu/drm/mediatek to
