When drivers works on top of an old bootcode, it is theoretically subjected to
MDC/MDIO failures since the MDIO clock is set in the beginning of each sequence,
rather than per CL45 command. On rare cases an old bootcodes may change that in
the middle, so to address that, the MDIO clock is set for each CL45 access.
In addition, setting the MDIO clock is now done per EMAC base, and
not per port number, since a specific port can potentially use both EMACs for
different PHY accesses.

Per measurements, the SFP+ suffered from small current leakage in two cases:
- When no module was plugged and TX laser was disabled. The fix was to enable
it, and when module is plugged in, check if it needs to be disabled.
- When over-current event occurs due to invalid SFP+ module, the HW basically
shuts down the current for this module, but the SW needs to complete this
by issuing a power down via a GPIO.

Taking PHY lock is not required on some older designs, but we are removing this
complication and always taking it since it is always required on newer designs
and does not worth the code complication on the older boards.
Taking PHY lock was initially required only on specific boards which had their
MDC/MDIO bus crossed, but since this lock is now always required, for example,
when NCSI is present, the PHY lock will always be taken.

To: David Miller; +Cc: netdev, Yaniv Rosner, Eilon Greenstein
This patch makes some cosmetic changes to the code:
1. Code alignment.
2. Merge read-modify-write into a single function (read_or_write /
read_and_write).
3. Merge several write registers into a for-loop write using a static array.
4. Remove empty lines.
5. Fix comments.
