* Fix overflow in WPM calculations.
First, the "fresh" WPM calculation could end up being up to 12000 (with
default `WPM_ESTIMATED_WORD_SIZE`) if keys were pressed more or less
simultaneously. This value has now been clamped down to 255, in effect
clamping WPM to its max value of 255.
Second, with `WPM_ALLOW_COUNT_REGRESSION` enabled, it was possible to
regress the WPM below 0 (i.e. to 255) by just repeatedly pressing
backspace.
* Fix WPM being limited to 235 due to float/int logic.
After a USB Reset event the device must, according to the spec wake up
from any suspend state, so the Configured event that arrives afterwards
should be interpreted as an implicit wakeup.
* Remove the #10088 hotfix for K20x MCU:s.
It seems to _cause_ the issue it intended to solve there.
* Cleaner way of removing #10088 hotfix.
Now only affects Ergodox Infinity, Whitefox and K-type, though.
Switches over Ergodox Infinity to the `IC_TEENSY_3_1` board, since that
was a nice place to implement the `restart_usb_driver` override.
However, I would guess this issue is present for other K20x/Teensy 3.1
boards as well...
* Fix comment regarding `IC_TEENSY_3_1` for all keyboards using it.
Two occurrences of `MATRIX_ROWS` weren't properly changed to
`ROWS_PER_HAND` in #13330, causing a crash during boot on at least my
Ergodox Infinity (including #13481).
