generic: mt7530: set CPU port to fallback mode
Currently, setting a bridge's self PVID to other value and deleting
the default VID 1 renders untagged ports of that VLAN unable to talk to
the CPU port:
bridge vlan add dev br0 vid 2 pvid untagged self
bridge vlan del dev br0 vid 1 self
bridge vlan add dev sw0p0 vid 2 pvid untagged
bridge vlan del dev sw0p0 vid 1
# br0 cannot send untagged frames out of sw0p0 anymore
That is because the CPU port is set to security mode and its PVID is
still 1, and untagged frames are dropped due to VLAN member violation.
Set the CPU port to fallback mode so untagged frames can pass through.
