word_in_value shouldn't be able to be used without being initialized,
so just initialize it to make GCC 5.3 happy. It's configured separately
in the (last_write_pointer & 3) and (!(last_write_pointer & 3)) paths,
so it can't actually slip through uninitialized.
There is probably a way to rwrite this that won't confuse GCC as much,
but I haven't found it yet. The solutions I did try generally ended
up increasing the binary size, so I'm falling back to just initializing
the variable.
chip/g/i2cs.c: In function '_i2cs_write_complete_int':
chip/g/i2cs.c:178:19: error: 'word_in_value' may be used uninitialized
in this function [-Werror=maybe-uninitialized]
This does not change the size of any ec.*.flat file.
BRANCH=none
BUG=none
TEST=build succeeds under GCC 4.9.2, 5.3 and 6.2
