am335x: TSC & ADC reworking including DT pieces, take 4

[Sebastian Andrzej Siewior]

I believe the whole thing should go via the MFD tree. It touches also
input & iio subsystem. I collected ACKs where I got some in the meantime.

I added Lee Jones because I hear no sign of life from Samuel.

The following changes since commit d683b96b072dc4680fc74964eca77e6a23d1fa6e:

  iio/ti_am335x_adc: check if we found the value (2013-06-11 13:11:35 +0200)

----------------------------------------------------------------
A complete refurbished series inclunding:
- DT support for the MFD, TSC and ADC driver & platform device support,
  which has no users, has been killed.
- iio_map from last series is gone and replaced by proper nodes in the
  device tree.
- suspend fixes which means correct data structs are taken and no
  interrupt storm
- fifo split which should problem with TSC & ADC beeing used at the same
  time
- The ADC channels are now checked before blindly applied. That means the
  touch part reads X, Y and Z coordinates and does not mix them up. Same
  goes for the IIO ADC driver.
- The IIO ADC driver now creates files named in_voltageX_raw where X
  represents the ADC line instead of a number starting at 0. A read from
  this file can return -EBUSY in case touch is busy and the ADC didn't
  collect a value.
