Since commit 6384fd "ARM: pxa: rename IRQ_GPIO to PXA_GPIO_TO_IRQ",
I got buid errors due to implicit declaration of function 'IRQ_GPIO'.

Use common gpio_to_irq() to replace machine dependant macro IRQ_GPIO().

Some files use GPIOF_ macros but don't include the header file
for them.  These macros are being moved to <linux/gpio.h>, so add
includes for <linux/gpio.h> where needed.

Use gpio_request_array() / gpio_free_array(), this makes the code
cleaner and less error prone.
