net: dsa: mv88e6xxx: rework ATU Remove
Add a fresh documented implementation of the ATU Move operation, and use
it to replace the current ATU Remove operation.
Note that not all Marvell switch chip support the ATU Move operation.
For those supporting it, the number of bits used to mask the destination
port may vary. 6352 and such use 4-bit, while 6390 use 5-bit. Thus add a
new atu_move_port_mask member in the info structure to describe the
presence and variant of ATU Move operation.
Note that the ATU Move operation is not documented in the 6185 datasheet
but the chip does support the operation.
All remaining _mv88e6xxx_atu_* functions are now unused as well as the
MV88E6XXX_FLAG_G1_ATU_FID flag, thus remove them.
