Arthur Heymans 4cc9b6c78d usbdebug: Initialize the HW once in CAR stages 
The EHCI hardware needs to be initialized only once during CAR stages.
Some exception need to be made when a blob messes with the EHCI
hardware. To achieve this add a fixed location in the car.ld linker
script such that the ehci debug information can be shared across CAR
stages.

Currently this means only romstage and bootblock, but verstage can
also be hooked up later on.

Tested on google/peppy: Both the bootblock and the romstage properly
output console.
