drm/msm/hdmi: Convert PHY files according to new design
Remove the old PHY ops managed by hdmi_platform_config and use them as ops provided by the HDMI PHY driver. Remove the old HDMI 8960 PLL code that used the top level HDMI TX mmio base. NOTE: With this commit, HDMI functionality will break until the HDMI PHY/PLL register offsets in hdmi.xml.h aren't updated to be used as separate domains.
