The atmega168 doesn't have enough flash space to fit all features -
disable the "bit banging" interfaces to make room.

The bank_id was calculated erroneously. Also unify gpio_in_setup and gpio_out_setup a bit. Also disable make flash for the sam4e8e port as it currently references a version of bossac that is not present on all systems.

This can be flashed to e.g. the duet wifi using bossac. It requires a
later version as is currently included in the klipper repo (1.8
vs. 1.2). Comms are currently via UART0 only, USB serial is still TBD

It's common for boards to have restrictions on the type of each
endpoint. So, make it possible for the board to select the endpoint
ids for each endpoint.

No need to include separate cmsis files from the mbed project - the
standard CMSIS_5 files work fine.

Update the sam3x8e port use the most recent SAM3X CMSIS files from
Atmel. The Atmel files appear to have a more consistent license and
it is unclear if there were Arduino specific changes in the CMSIS
files obtained from the Arduino repo.

Send the temperature before checking for an out of range error (that
makes it easier to debug).
The query_thermocouple clock parameter is unpredictable and a value of
zero can't be used to disable the query - use rest_ticks instead.

Change the simulator to use the generic timer_irq.c and serial_irq.c
code for (dummy) timer and io handling. This is just to make the code
a better example for other developers (most micro-controllers will use
the timer_irq.c and serial_irq.c code).

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

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 a command that can immediately set the value of a digital output

The AVR requires that the SS pin be an output pin for correct SPI
operation. Some boards use the SS pin to control devices separate
from SPI, however. Don't change the output level if the pin is
already an output, and prefer setting it low if it is not already an
output pin.

The PRU code size has grown too close to the maximum - remove the ADC
code to reduce its overall size. (On the beaglebone, the Linux
process can, and typically does, do the ADC reading.)

It appears the st7920 requires a longer delay when switching from
command to data mode (and vice-versa). Slower MCUs don't show a
problem because the klipper command processing time results in a
sufficient delay. However, some of the faster MCUs can process
klipper commands fast enough that the next st7920 transfer is sent too
fast. Add an additional delay to account for this.
