CBMEM console: Fix buffer without EARLY_CBMEM_INIT
On S3 resume, CBMEM_ID_CONSOLE from previous boot is found in ramstage,
even when romstage did not create it. So buffer did not get cleared
on S3 resume path.
Also do not allocate for preram_cbmem_console in CAR when there
are no means to back it up to ram.
