cbmem console: reduce temporary buffer size for dynamic CBMEM

When using dynamic CBMEM the CBMEM area is initialized before
    entering ram stage, and so we need a way smaller temporary buffer
    for the CBMEM console during early bits of ram stage. In practice
    around 256 bytes are needed, but keep the buffer at 1k so we make
    sure we don't run out.
