[PATCH V2 2/2] extcon: usb-gpio: Remove disable irq operation in system sleep.

[PATCH V2 2/2] extcon: usb-gpio: Remove disable irq operation in system sleep.

[Bruce Chen]

From: Bruce Chen <bruce.chen@unisoc.com>

If disable vbus/id irq, it will lead to wakeup system fail
in unisoc platform. In unisoc platform, Irq enable and irq
wakeup are the same interrupt line. So remove disable vbus/id
irq operation is a way to solve the issue.
