extcon: axp288: Convert to using managed resources
Use resource managed functions devm_usb_get_phy and devm_gpio_request to make error path simpler. To be compatible the change, various gotos are replaced with direct returns and unnecessary label gpio_req_failed is dropped. Also, remove function axp288_extcon_remove as it is now redundant.
