Subject: [PATCH v2 2/9] wlcore: use irq_flags in pdata instead of hiding it behind a quirk
The platform_quirk element in the platform data was used to change the
way the IRQ is triggered. When set, the EDGE_IRQ quirk would change
the irqflags used and treat edge trigger differently from the rest.
Instead of hiding this irq flag setting behind the quirk, export the
whole irq_flags element and let the board file define what to use.
This will be more meaningful than driver-specific quirks when we
switch to DT.
