cbmem console: reduce temporary buffer size for dynamic CBMEM

Browse source 
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.
