platform/x86: int3472: Increase handshake GPIO delay to 200 ms

There have been several reports of the sensor not properly powering on,
on laptops where an INT3472 handshake GPIO is used. Both with ov08x40 and
hi556 sensors.

Testing has shown that a delay of 200 ms is necessary in some cases.
The handshake GPIO is typically used to signal an extra bridge or other IC
with that IC running the full sensor power sequence based on the handshake
signal and also possible controlling I2C pass-through.

It seems that in some cases that extra IC takes up to 200 ms to before
the sensor is fully powered up and ready for I2C communication.

With the default handshake signal delay increased to 200 ms the quirk to
increase it to 45 ms for the ov08x40 is no longer necessary and is actually
undesirable since some ov08x40 setups also need the longer delay, drop it.
