net: phy: mscc: coma mode disabled for VSC8514
The 'coma mode' (configurable through sw or hw) provides an
optional feature that may be used to control when the PHYs become active.
The typical usage is to synchronize the link-up time across
all PHY instances. This patch releases coma mode if not done by hardware,
otherwise the phys will not link-up.

net: phy: mscc: improved serdes calibration applied to VSC8514
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.

net: phy: mscc: remove the use of .ack_interrupt()
In preparation of removing the .ack_interrupt() callback, we must replace
its occurrences (aka phy_clear_interrupt), from the 2 places where it is
called from (phy_enable_interrupts and phy_disable_interrupts), with
equivalent functionality.
This means that clearing interrupts now becomes something that the PHY
driver is responsible of doing, before enabling interrupts and after
clearing them. Make this driver follow the new contract.

net: phy: mscc: implement generic .handle_interrupt() callback
In an attempt to actually support shared IRQs in phylib, we now move the
responsibility of triggering the phylib state machine or just returning
IRQ_NONE, based on the IRQ status register, to the PHY driver. Having
3 different IRQ handling callbacks (.handle_interrupt(),
.did_interrupt() and .ack_interrupt() ) is confusing so let the PHY
driver implement directly an IRQ handler like any other device driver.
Make this driver follow the new convention.
Also, remove the .did_interrupt() callback since it's not anymore used.
