phy: marvell: add RX training command

Browse Source 
This patch adds support for running RX training using new command called
"rx_training"
Usage:
rx_training - rx_training <cp id> <comphy id>

RX training allows to improve link quality (for SFI mode)
by running training sequence between us and the link partner,
this allows to reach better link quality then using static configuration.
