Subject: [PATCH v2 11/11] mfd: pm8xxx: revert "disassociate old virq if hwirq mapping already exists"

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 tested on an APQ8060 DragonBoard.
