Some P4080 rev1 errata work-arounds, notably erratum SERDES4, required a
bank soft-reset after the bank was configured and enabled, even though
enabling a bank causes it to reset. Because the reset was required for
multiple errata, it was not properly enclosed in an #ifdef, and so was
not removed with all the other rev1 errata work-arounds.
Erratum SERDES-8 says that the clocks for bank 3 needs to be enabled if
bank 2 is enabled, but this was not being done for SERDES protocols 0xF
and 0x10. The bank reset also happened to enable bank 3 (apparently an
undocumented feature). Simply removing the reset breaks these two
protocols.
It turns out that every time we call enable_bank(), we do want at least
one lane of the bank enabled, either because the bank is supposed to be
enabled, or because we need the clock from that bank enabled.
For erratum SERDES-A001, we don't want to modify srds_lpd_b[] when we
call enable_bank(), because that array is used elsewhere to determine if
the bank is available.
Note that the side effect of these changes is that the work-arounds for
these two errata are now linked. Specifically, if SERDES-A001 is
enabled, then we need SERDES-8 enabled as well.
Because this was the only SERDES bank soft-reset, there is no need to
implement a work-around for erratum SERDES-A003.
Also fix an off-by-one error in a printf().

Bank powerdown through RCW[SRDS_LPD_Bn] for XAUI on FM2 and SGMII on FM1
are swapped.
Erratum SERDES-A001 says that if bank two is kept disabled and after bank
three is enabled, then the PLL for bank three won't lock properly. The
work-around is to enable and then disable bank two after bank three is
enabled.

Part of the SERDES9 erratum work-around is to set some bits in the SerDes
TTLCR0 register for lanes configured as XAUI, SGMII, SRIO, or AURORA. The
current code does this only for XAUI, so extend it to the other protocols.

The work-around for P4080 erratum SERDES-8 requires all lanes of banks two
and three to be disabled (powered down) in the RCW. Display a warning
message if this is not the case.

Rework and add some new APIs to the fsl_corenet_serdes code for use by
erratum and drivers.
* Rename serdes_get_bank() to serdes_get_bank_by_lane()
* Add serdes_get_first_lane returns which SERDES lane is used by device

Add support for initializing the SERDES blocks on CoreNet style QoriQ
devices and the p4080 specific SERDES tables to know which actual
componetns are enabled.
Additionally, split out the Frame Manger (FMAN) into its specific ethernet
ports instead of gross level of the full FMAN.
