usb: Add st_usbfs_v2 for f0/l0 devices
Based on previous work, add a new driver for the v2 usb peripheral found on stm32f0 and l0 devices. Correspondingly, add a usb gadget zero test suite for the f0. L0 device level code isn't yet ready, but will add the test case when it moves in. Work by Frantisek Burian, Kuldeep Singh Dhaka, Robin Kreis, fenugrec and zyp on irc, and all those forgotten.
