[PATCH 9/9] mfd: pm8xxx: revert "disassociate old virq if hwirq mapping already exists"

[Brian Masney <masneyb@xxxxxxxxxxxxx>]

Now that ssbi-gpio is a proper hierarchical IRQ chip, and all in-tree
users of device tree have been updated, we can now drop the hack that
was introduced to disassociate the old Linux virq if a hwirq mapping
already exists. That patch was introduced to not break git bisect for
any existing boards.

This change was not tested on any actual hardware, however the same
change was made to spmi-pmic-arb.c and tested on a LG Nexus 5
(hammerhead) phone.
