spi: Fixes for v6.10

This pull request fixes two regressions that have been bubbling along
for a large part of this release.  One is a revert of the multi mode
support for the OMAP SPI controller, this introduced regressions on a
number of systems and while there has been progress on fixing those
we've not got something that works for everyone yet so let's just drop
the change for now.  The other is a series of fixes from David Lechner
for his recent message optimisation work, this interacted badly with
spi-mux which is altogether too clever with recursive use of the bus and
creates situations that hadn't been considered.

There are also a couple of small driver specific fixes, including one
more patch from David for sleep duration calculations in the AXI driver.
