[ARM] 4434/1: PXA: remove PXA_IRQ_SKIP
1. PXA_IRQ_SKIP is defined to be 7 on PXA25x so that the first IRQ
starts from zero. This makes IRQ numbering inconsistent between
PXA25x and PXA27x. Remove this macro so that the same IRQ_XXXXX
definition has the same value on both PXA25x and PXA27x.
2. make IRQ_SSP3..IRQ_PWRI2C valid only if PXA27x is defined, this
avoids unintentional use of these macros on PXA25x
