platform/x86: int3472: Increase ov08x40 handshake GPIO delay to 45 ms

On HP laptops with an ov08x40 sensor the 25 ms delay coming from Intel's
out of tree drivers is not enough. Testing has confirmed that 45 ms does
work.

Add a quirk to the int3472_gpio_map[] to increase the delay to 45 ms to fix
probing of the ov08x40 sensor failing on these laptops.

Note this only impacts laptops which actually use an ov08x40 sensor with
a handshake GPIO.
