iio: mxs-lradc: Do hardware initialization earlier 



We need to initialize hardware before registering the touchscreen. Else,
we end up setting registers in mxs_lradc_ts_open(), getting called just
after registering the touchscreen with input_register_device() and by
the end of mxs_lradc_probe(), we reset the LRADC block hence losing the
correct configuration.
