Cleanup README

Cleanup older notes from the README.  Move the part about disabling
auto-reset to towards the end under ‘older notes’ and add a comment
about how it shouldn’t be necessary.  Almost move the part about the
device profiles as they are builtin to ols-0.9.7 or newer.

- * NOTE:
- * If you are using the original SUMP client, or using the alternative client
- * without the device profiles, then you will get a "device not found" error.
- * You must DISABLE the Arduino auto reset feature to use this logic analyzer
- * code. There are various methods to do this, some boards have a jumper,
