a=openpgp; fpr=8F88381DD5C873E4AE487DA5199BF1243632046A Rework Qualcomm PMIC TCPM driver to allow different platform-specific implementations of the PD PHY interface. While majority of platforms has the same of register for the PD PHY, some obscure ones (PMI632) do not have real PD PHY support. Add proper interface between the main module and the PD PHY backend to allow switching the PD PHY implementation.

In future it will also be extended with support for the DisplayPort handling. It will also be reused later for such platforms as SDM660, SM6125, SM6150.

If the PHY uses two lanes for USB, it is symthom that it should use either a combo USB+DP or a USB-C PHY driver.
