[U-Boot] [PATCH] 85xx/b4860: Alternate serdes protocols for B4860/B4420

On B4860 and B4420, some serdes protocols can be used with LC VCO as
well as Ring VCO options.
Addded Alternate options with LC VCO for such protocols.
For example protocol 0x2a on srds 1 becomes 0x29 if it is LC VCO.
The alternate option has the same functionality as the original option;
the only difference being LC VCO rather than Ring VCO.
