Subject: [PATCH v2 2/3] gpiolib: debugfs: show linux irq number for gpios requested as irq

This patch updates GPIO debugfs code to show Linux IRQ number
for GPIOs requested as irq.

After this patch sys/kernel/debug/gpio will produce following output:
    ...
    GPIOs 160-191, platform/4805d000.gpio, gpio:
     gpio-171 ((null)              ) in  hi IRQ-209
