History
George Stark 90c6241860 iio: adc: meson: init voltage control bits 
Define and init voltage configuration bits. Those bits are inited in
vendor boot code (bl2, bl33) already so do it in the driver to not depend
on other code.

Introduced bits:
REG11[0] - selects Vref. 0 - calibration voltage, 1 - VDDA. txlx and later
           SoCs support VDDA or calibration voltage as Vref, but others
           support only calibration voltage. For newer platforms vendor
	   uses VDDA as default.
REG11[1] - reserved bit. g12a and later SoCs must write 1, others SoCs
           write 0.
REG11[5] - Vref voltage. 0 - 0.9v, 1 - 1.8v. g12a and later SoCs must
           write 0, others SoCs write 1.
REG11[6] - selects common-mode voltage, 0: from AVDD, 1: from Vref.
           g12a and later SoCs must write 0, others SoCs write 1.
