usbdebug: Fix boards without EARLY_CBMEM_INIT

The main usbdebug file lib/usbdebug.c was removed from romstage
    build with commit f8bf5a10 but the chipset-specific parts were not,
    leading to unresolved symbol errors for AMD platforms.

Add a silent Kconfig variable USBDEBUG_IN_ROMSTAGE for convenient
    use of this feature.
