iio: mxs-lradc: Fix misuse of iio->trig

When reading IIO_CHAN_INFO_OFFSET, the return value of iio_channel_read() for
success will be IIO_VAL*, checking for 0 is not correct.
Without this fix the offset applied by iio drivers will be ignored when
converting a raw value to one in appropriate base units (e.g mV) in
a IIO client drivers that use iio_convert_raw_to_processed including
iio-hwmon.
Since the info_mask split, iio_channel_has_info() is not working correctly.
info_mask_separate and info_mask_shared_by_type, it is not possible to compare
them directly with the iio_chan_info_enum enum. Correct that bit using the BIT()

This patch fixes the following checkpatch warning:
WARNING: msleep < 20ms can sleep for up to 20ms
The implementation of msleep() is based on jiffies timeout
subsystem. Hence, its resolution is constrained by the value
of HZ tick rate. When HZ variable is configured to 100,
the jiffies variable is updated every 10 ms, so a timeout
of 1ms cannot be met using jiffies (it will be rounded up
to 10ms).

usleep_range() uses hrtimers subsystem which is not bound
to HZ value and can provide microsecond-level resolution.
