Dario Binacchi 16ff93557d Input: ti_am335x_tsc - set ADCREFM for X configuration
[ Upstream commit 73cca71a90 ]

As reported by the STEPCONFIG[1-16] registered field descriptions of the
TI reference manual, for the ADC "in single ended, SEL_INM_SWC_3_0 must
be 1xxx".

Unlike the Y and Z coordinates, this bit has not been set for the step
configuration registers used to sample the X coordinate.

Fixes: 1b8be32e69 ("Input: add support for TI Touchscreen controller")
