Fix Ergodox EZ Matrix scan

Specifically, row 11 was wrong.

Thanks algernon, for catching that.

@fdidron thoughts?

@ezuk @drashna looks good to me.

I think I figured out why the keyboard works either way: PORTD doesn't appear to matter, only DDRD. According to the comments in unselect_row and select_row, the port bit is always zero. With that in mind, the whole code could be simplified by removing the PORT settings alltogether (and just zeroing them on matrix_init, which unselect_row already does).

@algernon on a semi-related note: I think your keymap might be breaking CI right now? :) Did you happen to notice?

[algernon]

I did, #4465 was submitted as a result.
