Aleksandr Mishin cd75721984 gpio: davinci: Validate the obtained number of IRQs
[ Upstream commit 7aa9b96e9a73e4ec1771492d0527bd5fc5ef9164 ]

Value of pdata->gpio_unbanked is taken from Device Tree. In case of broken
DT due to any error this value can be any. Without this value validation
there can be out of chips->irqs array boundaries access in
davinci_gpio_probe().

Validate the obtained nirq value so that it won't exceed the maximum
number of IRQs per bank.

Found by Linux Verification Center (linuxtesting.org) with SVACE.

Fixes: eb3744a2dd ("gpio: davinci: Do not assume continuous IRQ numbering")
