Add code to parse the GPIO expander Device Tree node and extract platform

Add DT binding info in Documentation.

- v2 posted after quite a while, sorry for the delay!
Changes in v2:
- second gpeio-cell description corrected in Documentation
- interrupt controller description removed for now, will be added in a
follow up patch
- n_latch description updated
And it seems that the patch conflicts with
https://lkml.org/lkml/2013/8/26/248
:-/
:/
If we end up merging this one, I'd like to at least rename the DT n-latch
property to pin-initial-states as in my patch and update the documentation, as
I find it more explicit.
I think your patch is cleaner and more descriptive. The only thing which
I am not clear about in your patch is the extra work done in getting
ngpio, that should be available in i2c_device_id pointer argument in
probe(id points to the array pcf857x_id already available in the driver
with the number of gpios for each chip variant).
