mfd: ti_am335x: Drop am335x_tsc_se_update() from resume path

Browse source 
The update of the SE register in MFD doesn't look right as it has
nothing to do with it. The better place to do it is in TSC driver (which
is already doing it) and in the ADC driver which needs this only in the
continues mode.
