[Keyboard] id80: Transpose matrix to use faster COL2ROW routines (#8930)
* id80: Transpose matrix to use faster COL2ROW routines

Even the standard QMK matrix_scan() function can give about 2 times
higher scan rate (if compiled with optimizations enabled) if the COL2ROW
matrix layout is used instead of ROW2COL.  Although the ID80 PCB is
wired using the ROW2COL matrix layout, it is possible to transpose the
matrix from the QMK standpoint, so that "columns" would correspond to
horizontal connections, and "rows" would correspond to (mostly) vertical
connections; in this case the matrix could be handled as if it had the
COL2ROW layout.

The matrix layout change makes the older VIA JSON layout definition
incompatible, but the corresponding JSON was not yet accepted to the VIA
repository, so it should still be safe to make this change.

* id80: Remove obsolete comments

* The matrix description in the vendor-supplied JSON file for kbfirmware.com
* had 9 columns:
* { D0, D1, D2, D3, D5, D4, D6, D7, B4 }
* and 12 rows:
* { B7, B3, B2, B1, B0, E6, F0, F1, F4, F5, F6, F7 }
* However, the row 6 was completely empty, and the pin F0 was not actually
* routed anywhere on the PCB, therefore this row was removed to save some
* resources (the EEPROM space for dynamic keymaps is especially scarce).
*
* After doing the above change, the matrix was transposed (rows and columns
* were swapped), because a matrix with the COL2ROW layout can be scanned much
* more efficiently than a matrix with the ROW2COL layout (depending on various
* optimizations, the difference in scan rate can be over 2 times). Because of
* this, the "columns" in the matrix layout now mostly correspond to physical
* rows, and the "rows" have mostly vertical physical orientation.
