stm-st-stm32mp: fip-stm32mp: add OP-TEE USB FIP configuration 

The FIP flavor for OP-TEE + USB is managed in the meta-st-stm32mp layer through
the "optee-programmer-usb". However, since we do not require the additional
overhead introduced by the STM32CubeProgrammer tool, this commit introduces a
new FIP configuration based on OP-TEE for booting from USB.
