iic_acquire_bus can fail

avoid stack usage in match routine

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.

branches: 1.4.2;
- WBSIO_ID_W83627DHG and newer devices have 12bit device ID. So, change sioid
from 8bit to 16bit and check with it strictly.
- s/lm_match/nslm_match/
- split {wb,lm,def}_match() to XXX_match and XXX_attach().
- Rename lm_probe with lm_match and call {wb,nslm,def}_match() at the end of
the function to check strictly.
- NCT610[246]D is different from otehrs, so add new nct6102d_sensors[] table.
- Register offsets of vendor ID and chip id of NCT610[246]D are different
from others. When it failed reading vendor ID or chip ID, fallback to
NCT610[246]D's register offsets.
- Add debug messages.

Use uint8_t instead of int. No functional change.

branches: 1.2.2; 1.2.10; 1.2.16; 1.2.44; 1.2.64; 1.2.80;
Remove duplicated copy of the file - no idea where it came from.
