drivers: udc: implement udc_mcux_ehci and udc_mcux_ip3511

udc_mcux_ehci is based on the MCUX USB controller driver
(usb_device_ehci.c); udc_mcux_ip3511 is based on the
MCUX USB controller driver (usb_device_lpcip3511.c);
add related Kconfig and CMake; include the usb_phy.h path in
modules/hal_nxp/usb/CMakeLists.txt because udc_mcux.c use it;
add related macros to usb_device_config.h;
update CMakeLists for udc_mcux_ehci and udc_mcux_ip3511.
