X-Git-Tag: firefly_0821_release~7613^2~3714^2~52

x86: Convert irq_chip access to new functions

Before moving the irq chips to the new functions, fixup direct callers.

The cpu offline irq fixup code needs to become generic and archs need
to honour the "force" flag as an indicator, but that's for later.
