    CBMEM console: Fix and enhance pre-RAM support
    
    Use the value of CONSOLE_PRERAM_BUFFER_SIZE to determine if we can
    do CBMEM console in bootblock and romstage. Kconfig forces it to zero
    if _BASE is unset or we cannot do CAR migration on x86.
    
    Add CBMEM console to bootblock, except for x86. Only one of bootblock
    and romstage clears the pre-RAM buffer.
    
    To start with empty console log on S3 wakeup, ramstage now clears
    previous contents of CBMEM buffer if there was no pre-RAM buffer.
    
    Unify Kconfig variable naming.
    
    TODO: ARM configurations do not define PRERAM_BUFFER_BASE values.
