* prefer passing data to irq handler using 'void *dev_id' argument
* remove references to 'irq' function arg that either duplicate
a member of our private struct, or are always [true|false].
* add linux/interrupt.h include where needed
This change's main purpose is to prepare for the patchset in
jgarzik/misc-2.6.git#irq-remove, that explores removal of the
never-used 'irq' argument in each interrupt handler.
