ARM: OMAP1: ams-delta-fiq: Fix missing irq_ack
Non-serio path of Amstrad Delta FIQ deferred handler depended on
irq_ack() method provided by OMAP GPIO driver. That method has been
removed by commit 693de831c6e5 ("gpio: omap: remove irq_ack method").
Remove useless code from the deferred handler and reimplement the
missing operation inside the base FIQ handler.
Should another dependency - irq_unmask() - be ever removed from the OMAP
GPIO driver, WARN once if missing.
