[RFC PATCH 03/10] genirq: Employ ack_irq() and eoi_irq() where relevant

[Valentin Schneider]

This can easily be coccinelle'd to replace all existing chip->irq_{ack,
eoi} callsites, however not all callsites benefit from this
replacement: fasteoi flow handlers for instance only deal with an
->irq_eoi() callback. Instead, only patch callsites that can benefit from
the added functionality.
