stmmac: intel: Add PSE and PCH PTP clock source selection
Intel mGbE variant implemented in EHL and TGL can be set to select different clock frequency based on GPO bits in MAC_GPIO_STATUS register. We introduce a new "void (*ptp_clk_freq_config)(void *priv)" in platform data so that if a platform is required to configure the frequency of clock source, in this case Intel mGBE does, the platform-specific configuration of the PTP clock setting is done when stmmac_ptp_register() is called.
