====================
net: dsa: mt7530: modernize MIB handling + fix

This small series modernize MIB handling for MT7530 and also
implement .get_stats64.

It was reported that kernel and Switch MIB desync in scenario where
a packet is forwarded from a port to another. In such case, the
forwarding is offloaded and the kernel is not aware of the
transmitted packet. To handle this, read the counter directly
from Switch registers.
