The Trinamic specs aren't consistent with upper vs lower case, which
can be confusing. Improve clarity by using lower case names
consistently in the code. Register names will continue to use all
upper case naming in the code.
Update the SET_TMC_FIELD command to automatically convert field names
to lower case.

The tmc2130 (and tmc5160) will respond back with the value written
during the next SPI command. Use this feature to verify that the
value written matches the value sent.

Check the status of all Trinamic stepper motor drivers once a second.
If the driver reports an error then invoke a shutdown. Also log any
serious warnings.

The tmc5160 field formatters were mostly duplicates of the tmc2130 -
add the "reset" field to tmc2130.py so both drivers have similar
reporting.

Refactor the tmc driver implementations so that there is a single

Add support for enabling the stepper via the communication channel.
This improves support for boards with a shared enable line.

A print_time of zero may translate to a negative clock on a secondary
micro-controller, which would cause an internal error. Change the
code to pass a real print_time or None if it is not needed.

Only the tmc2208 driver needs special read register translation logic.
Rework the code so a default implementation is available for all the
other drivers.

Introduce TMCMicrostepHelper and TMCStealthchopHelper helper code that
uses the mcu_tmc interface. Update the callers to use these new
helpers.

Perform the register initialization directly from TMCCommandHelper and
perform it during the "connect" phase. This unifies the register
setup for the TMC2130, TMC2208, TMC2660, and TMC5160.

Use the field names from the trinamic specification. This makes the

Use the field helper to simplify the bit manipulation in the driver.
This also enables the extended DUMP_TMC output.

Change the name of the config registration method and pass an explicit
reference to the callback to the new method. This makes the
relationship between mcu registration and build_config() more clear in
the calling code.
