[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.
