The current IB serdes calibration algorithm (performed by the onboard 8051)
has proven to be unstable for the VSC8514 QSGMII phy.
A new algorithm has been developed based on
'Frequency-offset Jittered-Injection' or 'FoJi' method which solves
all known issues.  This patch disables the 8051 algorithm and
replaces it with the new FoJi algorithm.
The calibration is now performed in a new file (mscc_serdes.c),
which can act as an placeholder for future serdes configurations.
