iio: hid-sensors: move triggered buffer setup into hid_sensor_setup_trigger 

The main intent here is to get rid of the iio_buffer_set_attrs() helper, or
at least rework it's usage a bit.
The problem with that helper is that it needs a pointer to the buffer,
which makes supporting multiple buffers per IIO device a bit more
cumbersome.

The hid_sensor_setup_trigger() is pretty much used in the same way:
- iio_triggered_buffer_setup() gets called before
- then hid_sensor_setup_trigger() and hid_sensor_setup_batch_mode() gets
  called which may attach some fifo attributes

This change merges the 2 together under the hid_sensor_setup_trigger()
function. Only the &iio_pollfunc_store_time is passed to all devices, so
it's not even required to pass it explicitly outside of the common
hid_sensor_setup_trigger() function.

Moving the devm_iio_triggered_buffer_setup/cleanup() calls into the common
place code can help the rework of the buffer code, since it is in one
place.

One detail of the change is that there are 2 drivers that use
devm_iio_triggered_buffer_setup(). That function gets implicitly
replaced with iio_triggered_buffer_setup()/cleanup(), but since all drivers
call both hid_sensor_setup_trigger9) & hid_sensor_remove_trigger() trigger,
the iio_triggered_buffer_cleanup() piggy backs on the
hid_sensor_remove_trigger() call, which should cover the cleanup.
