[PATCH v2 1/2] gpio: Increase ARCH_NR_GPIOs to 512

[Mika Westerberg <mika.westerberg@xxxxxxxxxxxxxxx>]

Some newer Intel SoCs, like Braswell already have more than 256 GPIOs
available so the default limit is exceeded. Instead of adding more
architecture specific gpio.h files with custom ARCH_NR_GPIOs we increase
the gpiolib default limit to be twice the current.

Signed-off-by: Mika Westerberg <mika.westerberg@xxxxxxxxxxxxxxx>

Changes to previous version is that now we increase the common limit
instead of adding x86 specific gpio.h
