[U-Boot] [PATCH] powerpc/t4rdb: Add alternate serdes protocols to align with A-007186

[Chunhe Lan]

A-007186: SerDes Ring VCO does not maintain lock
throughout specified temperature range.

Option 1 of the workaround states:
-------------------------------------
For all 1.25/2.5/5 GHz protocols, use LC VCO instead
of Ring VCO. Rather than selecting the SRDS_PRTCL_Sx
in the RCW, use the Alternate SRDS_PRTCL_Sx option.
The alternate option has the same functionality as
the original option; the only difference being LC VCO
rather than Ring VCO.

The alternate Protocols are:

Serdes1: 27 instead of 28
Serdes2: Not impacted
Serdes3: 1 instead of 2
Serdes4: 9 instead of 10
