cbmem_console: Remove "buffer_" prefix from all structure fields

Shorten field names of struct cbmem_console since saying "buffer_" in
front of everything is redundant and we can use the gained space to save
some line breaks in the code later. This also aligns the definition with
the version in libpayload.
