net: dsa: mv88e6xxx: rework jumbo size operation
Marvell chips have a Jumbo Mode to set the maximum frame size (MTU).
The mv88e6xxx_ops structure is meant to contain generic functionalities,
no driver logic. Change port_jumbo_config to port_set_jumbo_size setting
the mode from a given maximum size value.
There is no functional changes since we still use 10240 bytes.
At the same time, correctly clear all Jumbo Mode bits before writing.
