drivers/bitbang: silence scan-build warning
The array is partially initialized with buf_set_u32(,5,32,), then
the rest of the array is read from SWD.
But scan-build report the array to have garbage content after the
initialization, due to the offset of 5 bit that only inits part of
the first byte.
Silence the false positive from scan-build by initializing the
array.
