[ARM] pxa: fix interrupts number calculation when CONFIG_PXA_HAVE_ISA_IRQS=y
Commit d2c37068429b29d6549cf3486fc84b836689e122 ([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.
