Input: raydium_i2c_ts - do not ignore EPROBE_DEFER from gpiod_get_optional
We should not be ignoring -EPROBE_DEFER reported by devm_gpiod_get_optional(), but report it as any other error to the upper layers. While we are at it simplify check for the presence of reset GPIO and instead of using IS_ERR_OR_NULL just use boolean. Also do not return -ENOMEM from suspend handler when the device in bootloader mode as that does not make sense and switch to -EBUSY instead.
