Kevin O'Connor 473828ca6a command: Add command_decode_ptr() helper
Add a helper function to convert from a string buffer passed in the
args[] parameter to an actual pointer.  This avoids all the callers
needing to perfrom pointer manipulation.

Kevin O'Connor c2a08962b7 spicmds: Rework spi config commands
Rework the spi_config commands so that bus configuration and shutdown
message configuration is done separately from the main "config_spi"
command.  This makes the spi configuration more flexible.  It's now
possible to use software spi without a CS pin.  It's now possible to
define multiple SPI messages to send on a shutdown event.

Kevin O'Connor db4f0c24cd spicmds: Check for an incorrect mode in spicmds.c
Check the mode parameter in spicmds.c so that the mcu code does not
need to check it.

Gcc does a better job of inlining code if spidev_transfer() is
reworked slightly.

Grigori Goronzy ebd9035325 SPI: introduce spi_prepare function
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:
