usbdebug: Quirk for board aopen/dxplplusu
This ancient board with Intel e7505 invalidates cache while it does HW
scrubbing for ECC in romstage. This breaks usbdebug console and prevents
system from booting.
If both EARLY_CONSOLE and USBDEBUG are selected, skip ECC scrubbing under
these rare conditions to boot system.
