Some platforms may not have a HPD gpio line to detect Hot Plug signal from the connector. They need to rely only on reading REG_HDMI_HPD_INT_STATUS for HPD.

Modify hdmi_connector_detect logic such that it checks for HPD only using the status register if there is no HPD gpio.

Add a helper to initialize PLL in the PHY driver. HDMI PLLs are going to have their own mmio base different from that of PHY.

For the clock code in hdmi_phy_8960.c, some changes were needed for it to work with the updated register offsets. Create a copy of the updated clock code in hdmi_pll_8960.c, instead of rewriting it in hdmi_phy_8960.c itself. This removes the need to place CONFIG_COMMON_CLOCK checks all around, makes the code more legible, and also removes some old checkpatch warnings with the original code.

The older hdmi pll clock ops in hdmi_phy_8960.c will be removed later. The driver will use these until the HDMI PHY/PLL register offsets aren't considered as separate domains (i.e. their offsets start from 0).

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.
