ice: introduce ice_ptp_init_phc function
When we enable support for E822 devices, there are some additional steps required to initialize the PTP hardware clock. To make this easier to implement as device-specific behavior, refactor the register setups in ice_ptp_init_owner to a new ice_ptp_init_phc function defined in ice_ptp_hw.c This function will have a common section, and an e810 specific sub-implementation. This will enable easily extending the functionality to cover the E822 specific setup required to initialize the hardware clock generation unit. It also makes it clear which steps are E810 specific vs which ones are necessary for all ice devices.
