Manuel Lauss 44f2c586a3 MIPS: Alchemy: Fix hang with high-frequency edge interrupts
The handle_edge_irq() flowhandler disables edge int sources which occur
too fast (i.e. another edge comes in before the irq handler function
had a chance to finish).  Currently, the mask_ack() callback does not
ack the edges in hardware, leading to an endless loop in the flowhandler
where it tries to shut up the irq source.

When I rewrote the alchemy IRQ code  I wrongly assumed the mask_ack()
callback was only used by the level flowhandler, hence it omitted the
(at the time pointless) edge acks.  Turned out I was wrong; so here
is a complete mask_ack implementation for Alchemy IC, which fixes
the above mentioned problem.
