net: phy: marvell10g: add MDI swap reporting

Browse Source 
Add reporting of the MDI swap to the Marvell 10G PHY driver by providing
a generic implementation for the standard 10GBASE-T pair swap register
and polarity register.  We also support reading the MDI swap status for
1G and below from a PCS register.
