The time between loading the helper image and starting to upload the
main firmware image should be at least 5 ms or so. We were doing an
msleep(1) before, and 1 ms appears to not be enough in almost all
cases, but building with HZ=100 has always masked this so far. Bumping
the msleep argument to 5 fixes firmware loading e.g. when HZ=1000.
Some firmware images need more than 200ms to initialize. Bump the
ready code timeout to 500ms to accommodate for this.
