fastboot: Move fastboot to drivers/fastboot
Separate CMD_FASTBOOT from FASTBOOT and move code and configuration to
drivers/fastboot.
Switch dependencies on FASTBOOT to USB_FUNCTION_FASTBOOT as anyone who wants
FASTBOOT before this series wants USB_FUNCTION_FASTBOOT. Split
USB_FUNCTION_FASTBOOT from FASTBOOT so they retain their existing
behaviour.
