usbdebug: Fix reserve in CAR
We need sizeof(struct ehci_dbg_info) of 88 but only
reserved 64 bytes. If usbdebug_hw_init() was called
late in romstage, for some builds it would corrupt
CAR_GLOBALs like console_inited variable and stop
logging anything.
Also change pointer initialisation such that
glob_dbg_info will hit garbage collection for
PRE_RAM stages.
