extcon: usb-gpio: increase debounce time
Testing on Colibri Evaluation board V3.x has shown even 50 ms not being
enough to avoid unloading and immediately reloading the EHCI USB host
controller driver upon OTG cable removal which is of course suboptimal.
This patch increases it to 100 ms which should leave enough safety
margin.
