Looking at section 8.6.1.1.69 in datasheets for both 5140 and 6140 (3140
doesn't support DRE). REG ADCX140_DSP_CFG1, field "DRE_AGC_SEL" (BIT 3)
it selects either DRE or AGC.
It states:
* 0 = DRE
* 1 = AGC
The control is called "DRE_ENABLE" and for it to be true it has to be
active low.
This commit will invert the control so "DRE_ENABLE" is active low.
