This patch consolidates the ab8500 mixed signal chip to expose the
same interface for register access as the ab3100, ab3550 and ab5500
chips. The ab8500_read() and ab8500_write() are removed and replaced
with abx500_get_register_interruptible() and
abx500_set_register_interruptible() respectively.

This patch need be applied across the subsystems so as not to break
bisection. Since it is mainly related to the core, the suggestion
is to bring this in through Sam:s tree.

Say yes here if you have the ABX500 Mixed Signal IC family
chips. This core driver expose register access functions.
