Kevin O'Connor 5bc47d9416 tmc2130: Use FieldHelper() to set/get driver fields
Use the field helper to simplify the bit manipulation in the driver.
This also enables the extended DUMP_TMC output.

Kevin O'Connor d088a7ca72 tmc2130: Share config reading helpers with tmc2208.py code
Add helper function for reading current, microsteps, and stealthchop
settings from the config file.  Use these helpers in both the tmc2130
and tmc2208 modules.

Move these helper functions to the FieldHelper class so that they can
be used by other Trinamic drivers.

lorf 54683c9535 tmc2208: Decode register fields in DUMP_TMC (#1156)
Report values of TMC2208 register fields in DUMP_TMC command to help in
tuning and diagnostics.

This also adds functions to refer to register fields by name for TMC drivers
and register mappings for TMC2208.

Kevin O'Connor def524bdf4 endstop_phase: Add support for detecting phase via TMC stepper drivers
The Trinamic stepper motor drivers are capable of reporting the
stepper phase - add support for using that capability to the
enddstop_phases module.

Kevin O'Connor 30013a1fb8 mcu: Rename add_config_object() to register_config_callback()
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.

Kevin O'Connor 273a98d39a pins: Explicitly pass can_invert and can_pullup to lookup_pin()
Don't pass pin_type to lookup_pin() - instead, if a pin can be
inverted or can have a pullup, then the caller must explicitly specify
that when calling lookup_pin().  This simplifies the code for the
cases where it is not valid to invert or pullup.

Explicitly pass the pin_type to setup_pin() and have ppins.setup_pin()
apply default pullup and invert flags.
