These modules need to depend on iic, not just on i2cexec. (They will
still recursively get i2cexec since the iic depends on it.)

Partial fix for kern/56772

Fix the serial number handling of the HTU21D chip and probably others.
Increase the number of read attempts as the HTU21D and probably others
do not respond as fast the actual SI70xx chip can.

Some HTU21D chips do not have a heater register and apparently no
heater element. Disable the heater features in the driver when that
condition is detected and let the attachment succeed. Also mention
that the SHT21 is another clone.

fix some more typos in comments/log messages, improve wording as well.

avoid double-free

branches: 1.6.4;
Make sure that we set sc->sc_sme to NULL in failure cases in order to avoid
calling sysmon_envsys_unregister() with an invalid struct when we detach.

branches: 1.5.12;
add missing break.

fairly sure this is correct, otherwise modelstr would be overwritten
with the next entry in this list..

branches: 1.4.2;
More cleanup to i2c autoconfiguration:

- Get all of the drivers onto the new match quality constants.
- Introduce a new helper function, iic_use_direct_match(), that has
all of the logic for direct-config matching. If it returns true,
the driver returns the match result (which may be 0). If it returns
false, the driver does indirect-config matching.
- iic_compat_match() now returns a weighted match quality; matches to
lower-indexed "compatible" device property are more-specific matches,
and return a better match quality accordingly.
