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.
