net: dsa: microchip: generic access to ksz9477 static and reserved table

Browse source

The ksz9477 and lan937x has few difference in the static and reserved
table register 0x041C. For the ksz9477 if the bit 0 is 1 - read
operation and 0 - write operation. But for lan937x bit 1:0 used for
selecting the read/write operation, 01 - write and 10 - read.
To use ksz9477 mdb add/del and enable_stp_addr for the lan937x, masks &
shifts are introduced for ksz9477 & lan937x in ksz_common.c. Then
updated the function with masks & shifts based on the switch instead of
hard coding it.
