After removing wrapper, pll and phy funcs from ti_hdmi_4xxx_ip.c, we are left
with OMAP4 HDMI core functions. Use these directly in hdmi.c rather than using
hdmi_ip_ops. Rename the core functions with a 'hdmi4' suffix.
We used to have hdmi_ip_ops so that one could support HDMI within a TI SoC which
had a non-DSS display subsytem. This however never got put into use, and hence
these ops aren't useful any more.
