[PATCH 2/3 RESEND] mfd: tc3589x: Reform device tree probing

[Lee Jones]

> This changes the following mechanisms in the TC3589x device tree
> probing path:
> 
> - Use the .of_match_table in struct device_driver to match the
>   device in the device tree.
> - Add matches for the proper compatible strings "toshiba,..."
>   and all sub-variants, just as is done for the .id matches.
> - Move over all the allocation of platform data etc to the
>   tc3589x_of_probe() function and follow the pattern of passing
>   a platform data pointer back, or an error pointer on error,
>   as found in the STMPE driver.
> - Match the new (proper) compatible strings for the GPIO and
>   keypad MFD cells.
> - Use of_device_is_compatible() rather than just !strcmp()
>   to discover which cells to instantiate.

Patch looks good to me. Is there any reason why we should rush this in
for v3.14, or is it okay to go to -next?
