State of a 32-bit Linear Feedback Shift Registers
(LFSR) that is used to implement CRC. This register
needs to be initialized by SW to provide the CRC seed
value.
The seed value should be aligned such that the more
significant bits (bit 31 and down) contain the seed
value and the less significant bits (bit 0 and up) contain
padding '0's.
Note that SW can write this field. This functionality can
be used prevent information leakage (through either
CRC_LFSR_CTL or CRC_REM_RESULT).
