mfd: New asic3 gpio configuration code
...
The ASIC3 GPIO configuration code is a bit obscure and hardly readable.
This patch changes it so that it is now more readable and understandable,
by being more explicit.

mfd: asic3 children platform data removal
...
Platform devices should be dynamically allocated, and each supported
device should have its own platform data.
For now we just remove this buggy code.

mfd: asic3 gpiolib support
...
ASIC3 is, among other things, a GPIO extender. We should thus have it
supporting the current gpiolib API.

ASIC3 driver
...
This is a patch for the Compaq ASIC3 multi function chip, found in many
PDAs (iPAQs, HTCs...).
It is a simplified version of Paul Sokolovsky's first proposal [1]. With
this code, it is basically a GPIO and IRQ expander. My plan is to add more
features once this patch gets reviewed and accepted.
