regulator: mc13892: Simplify implementation of mc13892_sw_regulator_set_voltage_sel()
Use mc13xxx_reg_rmw rather than a mc13xxx_reg_read and a mc13xxx_reg_write calls.
This logic to set MC13892_SWITCHERS0_SWxHI bit is pretty simple:
if (volt > 1375000)
set MC13892_SWITCHERS0_SWxHI bit
else if (volt < 1100000)
clear MC13892_SWITCHERS0_SWxHI bit
else
leave MC13892_SWITCHERS0_SWxHI bit untouched
We already know the selector, so we don't need to calculate the selector again.
