max44000: Remove scale from proximity

This is not implemented and doesn't really make sense because IIO
proximity is unit-less.

Remove IIO_CHAN_INFO_SCALE from info_mask because so that the _scale

staging: fsl-mc: add quirk handling for dpseci objects < 4.0

dpseci objects < 4.0 are not coherent-- in spite of the fact
that the MC reports them to be coherent in certain versions.
Add a special case to set the no shareability flag for dpseci
objects < 4.0.

staging: fsl-mc: get version of root dprc from MC hardware

The root dprc is discovered as a platform device in the device tree.  The
version of that dprc was previously set using hardcoded values from the API
header in the kernel).  This patch removes the use of the hardcoded version
numbers and instead reads the actual dprc version from the hardware.

staging: fsl-mc: don't use object versions to make binding decisions

Up until now if the object version expected by a driver (in the API header
file) did not match the actual object version in the MC hardware the bus
driver refused to bind the object to the driver or printed out WARN_ON
dumps.

This patch removes those checks, and the responsibility of object version
checking should now be done in the object drivers themselves.  If the actual
version discovered is not supported, the driver's probe function should fail.
Drivers should use version checks to support new features and provide
backwards compatibility if at all possible.

This patch also removes the checks that caused bus driver probing to fail
if the overall MC version discovered did not match the firmware version
from the API header...this was too strict.  The overall MC version is
informational like a release number, and continues to be printed in the
boot log.
