ENGR00327364 iMX6x: Ensure that the bandgap self-bias circuit is disabled after boot.rel_imx_3.0.101_4.1.1imx_v2009.08_3.0.35_4.1.0
The self-bias circuit is used by the bandgap during startup.
Once the bandgap has stabilized, the self-bias circuit should be
disabled for best noise performance of analog blocks.
Also this bit should be disabled before the chip enters STOP mode or
when ever the regular bandgap is disabled.
Backport from imx_v20014.04:fd572f16430d383a6c237f9fe9e96546c957a042
