[ARM] pxa: make pxa_gpio_irq_type() processor generic
The main issue here is that pxa3xx does not have GAFRx registers,
access directly to these registers should be avoided for pxa3xx:
1. introduce __gpio_is_occupied() to indicate the GAFRx and GPDRx
registers are already configured on pxa{25x,27x} while returns
0 always on pxa3xx
2. pxa_gpio_mode(gpio | GPIO_IN) is replaced directly with assign-
ment of GPDRx, the side effect of this change is that the pin
_must_ be configured before use, pxa_gpio_irq_type() will not
change the pin to GPIO, as this restriction is sane, esp. with
the new MFP framework
