On entry to ramstage CBMEM is looked for a copy of an already initialized
EHCI debug dongle state. If a copy is found, it contained the state before
CAR migration and the USB protocol data toggle can be out of sync. It's an
even/odd kind of a parity check, so roughly every other build would
show the problem as invalid first line: 'ug found in CBMEM.'
After CAR migration, re-direct the state changes to correct CBMEM table.
