Port over the changes from thorpej-i2c-spi-conf to thorpej-i2c-spi-conf2,
which is based on a newer HEAD revision.

ia->ia_cookie -> devhandle_to_of(device_handle(self))

Sync with HEAD.

Use DEVICE_COMPAT_EOL.

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

Use designated initializers and a consistent termination style in
compat_data[].

- No need to use I2C_F_POLL here.
- Properly propagate errors up the stack.

Sync with HEAD

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.

update from HEAD

Add FDT support

Always use polling mode for now, hummingbird doesn't work otherwise.

Sync with HEAD

dont read cs1/cs2 regs when reading clock, only use polling mode when cold, invert logic for century flag (1 means 1900, 0 means 2000), set dt_wday when reading clock

initialize CS1/CS2 regs, honour century flag, return an error on read if voltage low bit is set

use the inline bcdtobin and bintobcd directly instead through a macro.

merge to -current.

Add direct config support.

Per suggestion from tsutsui, convert to todr_[gs]ettime_ymdhms flavor.

Add pcf8563rtc(4), yet another I2C real time clock.
