soc/amd/cezanne: Disable CONSOLE_CBMEM_PRINT_PRE_BOOTBLOCK_CONTENTS

Now that PSP verstage can directly write to the UART, we no longer need
to manually dump the cbmem contents.

Ideally if we can get picasso to add support for mapping the UART, or
if we implement bit banging we can delete this functionality
completely.

BUG=b:215599230
TEST=Boot guybrush and verify verstage logs aren't printed twice
