The change will lose a bit of performance when performing IRQ ack/mask/unmask,but that's not too much after checking the result binary. This patch also removes the ugly #ifdef CONFIG_PXA27x .. #endif by carefully not to access those pxa{27x,3xx} specific registers, this is done by keeping an internal IRQ number variable. The pxa-regs.h is also modified so registers for IRQ > PXA_IRQ(31) are made public even if CONFIG_PXA{27x,3xx} isn't defined (for pxa25x's sake) The incorrect assumption in the original code that internal irq starts from 0 is also corrected by comparing with PXA_IRQ(0). "struct sys_device" for the IRQ are reduced into one single device on pxa{27x,3xx}.
