The device tree bindings are updated to document the resets phandle, and
the example is updated to match what is expected for both the reset and
clock phandle.
Note that the bindings should have always had the reset controller, as
the hardware is unusable without it.

With a nxp,se97 chip on an atmel sama5d31 board, the I2C adapter driver
is not always capable of avoiding the 25-35 ms timeout as specified by
the SMBUS protocol. This may cause silent corruption of the last bit of
any transfer, e.g. a one is read instead of a zero if the sensor chip
times out. This also affects the eeprom half of the nxp-se97 chip, where
this silent corruption was originally noticed. Other I2C adapters probably
suffer similar issues, e.g. bit-banging comes to mind as risky...
The SMBUS register in the nxp chip is not a standard Jedec register, but
it is not special to the nxp chips either, at least the atmel chips
have the same mechanism. Therefore, do not special case this on the
manufacturer, it is opt-in via the device property anyway.

As usual, this is the massive branch we have for each release. Lots of
various updates and additions of hardware descriptions on existing hardware,
as well as the usual additions of new boards and SoCs.
This is also the first release where we've started mixing 64- and 32-bit
DT updates in one branch.
(Specific details on what's actually here and new is pretty easy to tell
from the diffstat, so there's little point in duplicating listing it here.)
