a375: sample at reset: added new S@R field for DDR Bus width (16/32Bit)

	Added a new S@R field for DDR Bus width (S@R I2C = 0x4c, reg = 1, bit = 0)
	- This field is not sampled at reset to any internal register
	- mvCtrlSatRInit routine reads this fields directly from I2C
	  ( seperately from other S@R values from E8200/4 registers)
	- Added support for mvCtrlSatRWrite to access the 2nd I2C S@R register
