gpio: timberdale: fix off-by-one in IRQ type boundary check
timbgpio_irq_type() currently accepts offset == ngpio, violating
gpiolib's [0..ngpio-1] contract. This can lead to undefined behavior
when computing '1 << offset', and it is also inconsistent with users
that iterate with for_each_set_bit(..., ngpio).
Tighten the upper bound to reject offset == ngpio. No functional change
for in-range offsets.
