powerpc/b4860: Add workaround for errata A006384 and A006475
SerDes PLLs may not lock reliably at 5 G VCO configuration(A006384)
and at cold temperatures(A006475), workaround recalibrate the
PLLs with some SerDes configuration
Both these errata are only applicable for b4 rev1.
So, make workaround for these errata conditional,
depending upon soc version.
