[PATCH] HPET: handle multiple ACPI EXTENDED_IRQ resources

When the _CRS for a single HPET contains multiple EXTENDED_IRQ resources,
we overwrote hdp->hd_nirqs every time we found one.

So the driver worked when all the IRQs were described in a single
EXTENDED_IRQ resource, but failed when multiple resources were used.
(Strictly speaking, I think the latter is actually more correct, but both
styles have been used.)

Someday we should remove all the ACPI stuff from hpet.c and use PNP driver
registration instead.  But currently PNP_MAX_IRQ is 2, and HPETs often have
more IRQs.  Hint, hint, Adam :-)
