i2c: s3c2410: Mark expected switch fall-through
Mark switch cases where we are expecting to fall through.
This patch fixes the following warning:
drivers/i2c/busses/i2c-s3c2410.c: In function 'i2c_s3c_irq_nextbyte':
drivers/i2c/busses/i2c-s3c2410.c:431:6: warning: this statement may fall through [-Wimplicit-fallthrough=]
if (i2c->state == STATE_READ)
^
drivers/i2c/busses/i2c-s3c2410.c:439:2: note: here
case STATE_WRITE:
^~~~
Notice that, in this particular case, the code comment is
modified in accordance with what GCC is expecting to find.
