This splits out a per-SoC IRQ range handling, so that the
DB8500 and DB5500 SoC:s can reuse aproximately the same IRQ
range with the largest span setting the roof. The same change
is done for the boards, mutatis mutandis, with a new file for
the U5500 board.

When initialising a PMU, there is a check to protect against races with
other CPUs filling all of the available event slots. Since armpmu_add
checks that an event can be scheduled, we do not need to do this at
initialisation time. Furthermore the current code is broken because it
assumes that atomic_inc_not_zero will unconditionally increment
active_counts and then tries to decrement it again on failure.

This patch removes the broken, redundant code.
