[PATCH] usb: phy-generic: Use gpiod_set_value_cansleep

[Mike Looijmans]

The nop_reset and shutdown methods are called in a context that can sleep,
so use gpiod_set_value_cansleep instead of gpiod_set_value.

If you've connected the reset line to a GPIO expander, you'd get a kernel
"slowpath" warning with gpiod_set_value.
