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.
