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