Message:

minor: add const to cause parameter in sched_yield.

We never mutate the string parameter.

Gcc warning fixed:
`
hal/tsar_mips32/drivers/soclib_tty.c:183:30:
warning: passing argument 1 of 'sched_yield' discards 'const' qualifier from pointer target type [-Wdiscarded-qualifiers]

sched_yield( "TTY_TX_FIFO full" );
