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.

Make sure to configure DRVCONF with SDOFF=0 prior to writing DRVCTRL
as that field controls access to that register.

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 a get_register() method instead of get_response(). This makes the
tmc2660 class more similar to other TMC drivers. It also enables
DUMP_TMC to dump all the readable content.
Also, use the tmc2130.get_config_microsteps() helper.
