Fix issue where "unknown chip id!" is seen every other time

Previously when running the program, reading the chip version
would fail. Running the program a second time worked. This
sequence is repeated the next time st-flash/st-util is run.

Giving reset 10ms to complete before trying to read the chip
version resolves the issue.
