* Use the new debounce algorithm in dactyl/matrix.c [#2065]
This incorporates the fixed/optimized debounce code added to
quantum/matrix.c in:
* 508eddf8ba
* 4c6960835c
* 32f88c0717
* f403028974
* a06115df19
* Fix the row/column swap in dactyl [#2065]
With a column-driven keyboard, reading from the mcp23081 returns a
column-state, which takes some extra work to translate into the
row-state used in the actual matrix. The ergodox_ez code sidestepped
that problem by calling rows "columns" and columns "rows." With this
change, the dactyl now calls rows "rows" and columns "columns."
* Cleanup: variable names, documentation [#2065]
* Support MATRIX_MASKED in dactyl/matrix.c [#2065]
* Only unselect one col in unselect_col [#2065]
Bonus: saves one i2c transaction per matrix_scan!
* Implement COL2ROW in dactyl/matrix.c [#2065]
* Fix a typo in dactyl/matrix.c
This entirely doesn't matter. The PORT values are set during
init_keyboard and never change. They're repeatedly set to the same
thing. These PORT lines shouldn't even exist, but since they do, they
should at least look right.
* Implement COL_PINS/ROW_PINS for dactyl [#2065]
* Rename "mcp23018" to "expander" [#2065]
I honestly don't know whether/how well this code works with other I/O
expanders, but at least in theory, it should be generic enough to work
with others. Given that, the variable names shouldn't refer to a
specific model of expander.
* Remove matrix_power_up from dactyl/matrix.c [#2065]
It's commented out in quantum/matrix.c, and the dactyl has no power
up/down behavior beyond being unplugged (which goes to matrix_init), so
there's no sense keeping it around.
* Only initialize expander_input_mask once [#2065]
...and rename input_mask to expander_input_mask, since now that it isn't
scoped to init_expander it isn't clear that it's only for the expander.
