This moves all the header files related to the abx500 family into
a common include directory below mfd. From now on we place any
subchip header in that directory. Headers previously in e.g.
<linux/mfd/ab8500/gpio.h> get prefixed and are now e.g.
<linux/mfd/abx500/ab8500-gpio.h>. The top-level abstract interface
remains in <linux/mfd/abx500.h>.

With the pending module.h cleanup, these files will fail to compile,
unless they explicitly call out the include of this file.

This patch replaces the code for getting an unsigned long from a
userspace buffer by a simple call to kstroul_from_user.
This makes it easier to read and less error prone.

Partly for coding style reasons, but mostly because sparse warns on it.

This patch adds the possibility to read and write registers
via the debug_fs. It also adds ranges of registers sorted by bank
which makes it possible to read all defined registers in a bank.
