[PATCH edk2-platforms v3 2/5] Silicon/NXP/LS1043A: Fix the RCW bits' parsing

["Pankaj Bansal" <pankaj.bansal@nxp.com>]

From: Pankaj Bansal <pankaj.bansal@nxp.com>

For LS1043A SOC the DCFG registers are read in big endian format.
After Reading the registers in code we have the registers in Little
Endian Bit format i.e. LSBit 0.

However, the RCW bits in RCWSR registers in LS1043A SOC are in MSBit 0
format.

Currently, we are parsing the RCW bits in LE bit format i.e. LSBit 0.
Therefore, Fix the RCW bits' parsing as per MSBit 0.
