[PATCH 02/14] irq: Remove set_native_irq_info

[ebiederm@xmission.com (Eric W. Biederman)]

This patch replaces all instances of "set_native_irq_info(irq, mask)"
with "irq_desc[irq].affinity = mask".  The latter form is clearer
uses fewer abstractions, and makes access to this field uniform
accross different architectures.
