hvc_console: Allow backends to set I/O buffer size
To allow HVC backends to set the I/O buffer sizes to values that are most
efficient for the backend, change the macro definitions where the buffer sizes
are set to be conditional on whether or not the macros are already defined.
Also, rename the macros from N_OUTBUF to HVC_N_OUBUF and from N_INBUF to
HVC_N_INBUF.
Typical usage in the backend source file would be:
#define HVC_N_OUTBUF 32
#define HVC_N_INBUF 32
#include "hvc_console.h"
