net: dsa: microchip: Use regs[] to access REG_PTP_RTC_NANOSEC
Accesses to the PTP_RTC_NANOSEC register are done through a hardcoded
address which doesn't match with the KSZ8463's register layout.
Add a new entry for the PTP_RTC_NANOSEC register in the regs[] tables.
Use the regs[] table to retrieve the PTP_RTC_NANOSEC register address
when accessing it.
Remove the macro defining the address to prevent further use.
