No need to consult ia->ia_ncompat before calling iic_compatible_lookup().

Use DEVICE_COMPAT_EOL.

Since we're using designated initialisers for compat data, we should
use a completely empty initializer for the sentinel.

Change the device_compatible_match() function to only perform the match.
Introduce a device_compatible_lookup() function to return an entry based
on the same matching criteria (a'la of_search_compatible()).

Update iic_compatible_match() to reflect the above change, and introduce
iic_compatible_lookup().  This pattern is less awkward to use.

Change the device_compatible_entry struct to have a union of
a scalar value (uintptr_t value) and a pointer value (const void *data),
rather than just "uintptr_t data".  This eliminates the need for drivers
to cast this value, and doesn't lose const'ness of pointers assigned
to the field.

Update all of the users of this field to use the correct set of
designated initialisers for each specific case.

Mostly merge changes from HEAD upto 20200411

tsleep -> kpause

Oops, missed one more instance of unneeded-I2C_F_POLL.

seeprom_bootstrap_read(): no need to hard-code I2C_F_POLL here because
the i2c code will ensure it's there if the system is cold.

Support more than 128Kbit model.

Sync with HEAD

Remove the i2c "size" locator and corresponding property / attach arg.
It was a hack meant only for EEPROMs, which have another way to specify
size in the config directive ("flag" paramter), as well as a better way
to detect size based on "compatible" string.

Encode the size information in the compat data.

In my quest to make device_compatible_entry (and associated goo)
super-general, it turns out I also made it a little to cumbersome
to use (if my tired fingers are any indication).  So, this is a
course-correction -- one string per entry (like of_compat_data,
which it will soon replace), and remove the over-verbose macros.

Sync with HEAD

- Rename iic_compat_match() to iic_compatible_match() and change it
  to use the new device_compatible_match() routine.  A pointer to
  the matching device_compatible_entry is returned if a match is
  found.
- Adjust iic_use_direct_match() accordingly.
- i2c drivers now provide device_compatible_entry tables when performing
  direct-config matching.
- In the dsrtc driver, take advantage of this new capability to greatly
  simplify model selection.

(I'm coming for you next, of_compat_data...)

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.

Change (mostly mechanically) every cdevsw/bdevsw I can find to use

I have not built every extant kernel so I have probably broken at
least one build; however I've also found and fixed some wrong

Add "i2c-at34c02" AT34C02 EEPROM.  This is compatible with the AT24C02
