[ARM] 4559/1: pxa: make PXA_LAST_GPIO a run-time variable
This definition produces processor specific code in generic function pxa_gpio_mode(), thus creating inconsistencies for support of pxa25x and pxa27x in a single zImage. As David Brownell suggests, make it a run-time variable and initialize at run-time according to the number of GPIOs on the processor. For now the initialization happens in pxa_init_irq_gpio(), since there is already a parameter for that, besides, this is and MUST be earlier than any subsequent calls to pxa_gpio_mode().
