MIPS: sibyte: Declare the cfe_write() buffer as constant

The write() prototype expects a const char * as argument so declare
it as such.

Fixes the following build problem:

arch/mips/sibyte/common/cfe_console.c:23:5: error: passing argument 2 of
'cfe_write' discards 'const' qualifier from pointer target type [-Werror]
arch/mips/sibyte/common/cfe_console.c:34:4: error: passing argument 2 of
'cfe_write' makes pointer from integer without a cast [-Werror]
