This patch series simplifies TS handling of mxs-lradc.

These patches has been tested with i.MX23 and i.MX28 but without
a touchscreen. I added only a bogus touchscreen in devicetree.

It would be nice if someone with a real touchscreen could test it.

Changes in V3:
- remove dev.parent assignment as suggested by Dimitry
- add new patch to remove mxs_lradc_ts_unregister
- remove PM implementation from series in order to wait until 
  Ksenija has split the driver

Changes in V2:
- rebase on iio/testing since patch 2 and 3 from V1 has been applied
- also remove input_unregister_device in patch 1
- use mask of virtual channels for IRQ disabling in patch 2
