Kevin O'Connor f759df3cd7 endstop_phase: Convert to using tmc mcu_phase_offset
Now that the TMC drivers track the phase offset, use that to implement
endstop phase.

Kevin O'Connor 33dcb38297 tmc: Consistently use lower case for all TMC field names
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.

Kevin O'Connor b4fec8502c tmc2209: Set SENDDELAY=2 to avoid uart rx/tx errors
It looks like the tmc2209 chips have increased uart errors with the
default SENDDELAY of zero.  Increasing the SENDDELAY to two seems to
work around this issue.

Reported by @ReXT3D.

Kevin O'Connor 52b5ca182c tmc: Simplify internal DUMP_TMC interface
Only the tmc2208 driver needs special read register translation logic.
Rework the code so a default implementation is available for all the
other drivers.
