Another option is to change this patch to allow a SPI device driver to
request that the pumping thread be realtime but not to _force_ all
messages onto that thread. In the case of cros_ec this means a bunch
of code duplication (we need to create a thread
longer lose our priority when we get shunted over
to the message pumping thread (because we now always get shunted and
the thread is high priority).

This reverts commit 37a186225a0c020516bafad2727fdcdfc039a1e4.
We have a better solution in the patch ("platform/chrome: cros_ec_spi:
Force transfers to realtime priority"). Let's revert the uglier and
less reliable solution.

k OK to land it might be convenient if
they could be placed somewhere with a stable git hash?
Special thanks to Guenter Roeck for pointing out the "realtime"
feature of the SPI framework so I didn't re-invent the wheel. I have
no idea how I missed it. :-/

If a controller specifies that it needs high priority for sending
messages we should always schedule our transfers on the thread. If we
don't do this we'll do the transfer in the caller's context which
might not be very high priority.

When calculating the MMC phase we can just use clk_hw_get_rate()
instead of clk_get_rate(). This avoids recalculating the rate.
