drm/msm/hdmi: Fix wrong CTRL1 register used in writing info frames
Commit 384d2b03d0a1 ("drm/msm/hdmi: make use of the drm_connector_hdmi
framework") changed the unconditional register writes in few places to
updates: read, apply mask, write. The new code reads
REG_HDMI_INFOFRAME_CTRL1 register, applies fields/mask for
HDMI_INFOFRAME_CTRL0 register and finally writes to
HDMI_INFOFRAME_CTRL0. This difference between CTRL1 and CTRL0 looks
unintended and may result in wrong data being written to HDMI bridge
registers.
