4.20-stable review patch.  If anyone has any objections, please let me know.

------------------

[ Upstream commit f2105d42597f4d10e431b195d69e96dccaf9b012 ]

Fix link errors when CONFIG_FSL_USB2_OTG is enabled and USB_OTG_FSM is
set to module then the following link error occurs.

aarch64-linux-gnu-ld: drivers/usb/phy/phy-fsl-usb.o: in function `fsl_otg_ioctl':

Rework so that FSL_USB2_OTG depends on that the USB_OTG_FSM is builtin.
