50efacf671 gpio: pl061: fix IRQ handling for GPIOs >= PL061_GPIO_NR 
IRQ handling is wrong for any GPIO >= PL061_GPIO_NR.

Fix this by implementing and using a proper .to_irq method.

79d7f4ee23 gpio: pl061: fix probe error handling code 
Note that IRQ has not been initialized when kmalloc() fails.

Also, use DECLARE_BITMAP() to make the code clearer.

1e9c285998 gpio: driver for PrimeCell PL061 GPIO controller 
This is a driver for the ARM PrimeCell PL061 GPIO AMBA peripheral.  The
driver is implemented using the gpiolib framework.

This driver also includes support for the use of the PL061 as an interrupt
controller (secondary).
