net: dsa: microchip: correct KSZ8795 static MAC table access
The KSZ8795 driver code was modified to use on KSZ8863/73, which has
different register definitions. Some of the new KSZ8795 register
information are wrong compared to previous code.
KSZ8795 also behaves differently in that the STATIC_MAC_TABLE_USE_FID
and STATIC_MAC_TABLE_FID bits are off by 1 when doing MAC table reading
than writing. To compensate that a special code was added to shift the
register value by 1 before applying those bits. This is wrong when the
code is running on KSZ8863, so this special code is only executed when
KSZ8795 is detected.
