Arnd Bergmann 18b4b0ab65 firmware: ti_sci: fix strncat length check ...

commit 76cefef8e8 upstream.

gcc-7 notices that the length we pass to strncat is wrong:

drivers/firmware/ti_sci.c: In function 'ti_sci_probe':
drivers/firmware/ti_sci.c:204:32: error: specified bound 50 equals the size of the destination [-Werror=stringop-overflow=]

Instead of the total length, we must pass the length of the
remaining space here.
