clk/msm: fix HDMI PHY registers as per latest programming guide

HDMI PHY registers for MSM8998 chipset are not programmed as
per the latest hardware programming guide for the chipset.
This can affect HDMI electrical compliance test cases due
to low signal strength.

Fix up the HDMI PHY driver to use the latest values for the
PHY registers.
