Any platform can be dynamically probed for model and version number
provided the AB8500 MFD parent device pointer is available. This
patch obtains that pointer and stores it in a locally controlled
struct for later use.

Make use of the hierarchical interrupt rergister called
ITLatchHier1 - 3 also for the 8500 platform (currently the
hierarchical interrupt registers are used only for the 8540
and 9540 platforms). This will make the interrupt routing
go faster since fewer i2c reads need to made in the most
common cases.

As I am working on SPARSE_IRQ a number of implicit resource
grabs in the kernel become evident. For example, some includes
like <linux/irqs.h> would implicitly include <mach/irqs.h>
and then from there <mach/db8500-regs.h>.

In many cases it is masking the fact that drivers do not
properly use resources to pass their dependencies, base
addresses etc. So write explicit #include statements with
TODO items to have this fixed the proper way to all drivers
doing this.
