[ARM] pxa: fix interrupts number calculation when CONFIG_PXA_HAVE_ISA_IRQS=y

Browse Source 
Commit d2c3706842 ([ARM] pxa:
initialize default interrupt priority and use ICHP for IRQ handling)
broke ISA interrupt support on pxa27x/3xx.

In such a case, PXA_IRQ(0) != 0, and the IRQ number computed from
ICHP must be offset by PXA_IRQ(0).

Tested on an Arcom Zeus (pxa270), with both CONFIG_PXA_HAVE_ISA_IRQS
enabled and disabled.
