Subject: [PATCH 1/4] drm/mediatek: Move tz_disabled from mtk_hdmi_phy to mtk_hdmi driver

From: CK Hu <ck.hu@...iatek.com>

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.
