The SPI interface needs to be enabled and configured to the correct
settings of a given oid before CS is asserted. The new function
spi_prepare() allows ports to do that.
This port only introduces the new function in all ports with no
implementation and adds the call to the Klipper generic firmware code.
That means everything still works as before. Ports need to be changed
to fix the underlying issue.
Discussion about the motivation here:

Add basic SPI support and associated documentation.
v2: remove baud rate check, fix baud rate calculations
v3: finish transaction with BSY check, disable SPI when not in use

Add generic temperature smoothing to the Heater class. This is useful
to avoid min_extrude_temp and verify_heater errors due to measurement
noise.
Rename the pid_deriv_time config option to smooth_time so that the
smoothing amount need only be specified once.

Extend the ADC out of range check so that it is possible to sample
multiple times before going into a shutdown state. This reduces the
chance that measurement noise will cause an error. In an actual over
temperature (or under temperature event) it is expected that the
sensor will consistently report the problem, so extra checks for an
additional second or two should not substantially increase risk.

Add mcu support for periodically polling for a button press. Add host
code support for registering buttons and invoking callbacks for them.

Add the ability to register callbacks - both asynchronous (ie, from
another thread) and synchronous.

Add an ability to run a series of g-code commands from a reactor
callback that isn't part of the normal g-code command processing.

For some reason, the upper two pin definitions were missing. Found while
writing the port documentation.

Update the target temperature during the pid calibration. This gives
additional feedback to the user and it makes it less likely that a
verify_heater error will be raised during calibration.

Move the display code into its own directory. This is in preparation
for splitting it up into its own modules.
