The old "cooling-{min,max}-state" properties for thermal bindings were
ratified to "cooling-{min,max}-level" by commit eb168b70de ("of:
thermal: Fix inconsitency between cooling-*-state and cooling-*-level"),
which were later removed entirely by commit e04907dbc2 ("dt-bindings:
thermal: Remove "cooling-{min|max}-level" properties").
The pwm-fan binding, however, was apparently in-flight in parallel with
that ratification, and so managed to introduce an example of the old
properties which escaped the scope of the later cleanup and has thus
continued to be dutifully copied for new boards despite being useless.
Clean up these remaining undocumented anachronisms to minimise any
further confusion.

By default, cells in DT are 32-bit in size. The driver reads "ti,mode"
using the function of_property_read_u8() which causes the value to be
read incorrectly in little-endian architectures if the size is not
specified.
Make it explicit in the binding documentation that this prorperty must
be set as a 8-bit value.

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.

This is also the first release where we've started mixing 64- and 32-bit

(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.)
