[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
