NXP SoCs supports different serdes protocols using reset
configuration word (RCW).
Based on serdes protocol value in reset configuration word (RCW)
different IP blocks gets enabled in HW.
This patch series implements SerDesHelperLib and provide SoC specific
serdes configuration for LS1043A, which can be used by different IPs
(Ex: PCIe) to know the enabled interfaces and perform the required
initialization.
