usb: phy: gpio-vbus: fix deferred probe from __init
Move probe out of __init section and don't use platform_driver_probe which cannot be used with deferred probing. Since commit e9354576 ("gpiolib: Defer failed gpio requests by default") and 04bf3011 ("regulator: Support driver probe deferral") this driver might return -EPROBE_DEFER if a gpio_request or regulator_get fails.
