====================
ocelot phylink fixes

When the ocelot driver was migrated to phylink, 520544871945 ("net:
mscc: ocelot: convert to phylink") there were two additional writes to
registers that became stale. One write was to DEV_CLOCK_CFG and one was
to ANA_PFC_PCF_CFG.

Both of these writes referenced the variable "speed" which originally
was set to OCELOT_SPEED_{10,100,1000,2500}. These macros expand to
values of 3, 2, 1, or 0, respectively. After the update, the variable
speed is set to SPEED_{10,100,1000,2500} which expand to 10, 100, 1000,
and 2500. So invalid values were getting written to the two registers,
which would lead to either a lack of functionality or undefined
funcationality.

Fixing these values was the intent of v1 of this patch set - submitted
as "[PATCH v1 net] net: ethernet: mscc: ocelot: bug fix when writing MAC
speed"

During that review it was determined that both writes were actually
unnecessary. DEV_CLOCK_CFG is a duplicate write, so can be removed
entirely. This was accidentally submitted as as a new, lone patch titled
"[PATCH v1 net] net: mscc: ocelot: remove buggy duplicate write to
DEV_CLOCK_CFG". This is part of what is considered v2 of this patch set.

Additionally, the write to ANA_PFC_PFC_CFG is also unnecessary. Priority
flow contol is disabled, so configuring it is useless and should be
removed. This was also submitted as a new, lone patch titled "[PATCH v1
net] net: mscc: ocelot: remove buggy and useless write to ANA_PFC_PFC_CFG".
This is the rest of what is considered v2 of this patch set.

v3
Identical to v2, but fixes the patch numbering to v3 and submitting the
two changes as a patch set.

v2
Note: I misunderstood and submitted two new "v1" patches instead of a
single "v2" patch set.
- Remove the buggy writes altogher
