CBMEM console: Prevent buffer overrun

Make sure memcpy target and a possible message telling log was truncated
    stay within the allocated region for CBMEM console.

This fixes observed CBMEM corruption on platforms that do not use CBMEM
    console during romstage. Those platforms will need an additional fix to
    reset cursor position to zero on s3 resume.
