pn80t: clean up timing and power

This change does a bit of clean up:
- ETU is reduced by a factor of 7 to increase the poll interval to 1ms.
- Reset will use a soft-reset unless there is an ese_error()
- Common doesn't wait for gpio/power resets and lets the platform handle that.
- nq-nci doesn't sleep atfer power up since the kernel handles it.
- Cleaned up more error checking in cooldown.

Test: integration tests pass
