Lower the tick rate from 10kHz to 1kHz (otherwise all the extra interrupts
reduce the achievable scan rate). Enable the WAIT_US_TIMER using GPT TIM3.

Observed scan rate on the K320 is increased from 625Hz to 2090-2120Hz.

* Convert some more boards to Matrix Lite (qmk#15489)

* Fix for SPI write timing in PMW3360 driver (qmk#15519)

Timing does not match Pixart documentation for this sensor (may have been carried forward from adns9800).
Not aware of any issues coming from this currently.
It should only cause issues when writing to multiple registers in succession which currently only happens during initialization for the PMW3360.
This should prevent future issues with write operations if other features of the sensor are added.

* Format code according to conventions (qmk#15593)

* pwm3360 driver cleanup and diff reduction to adns9800 (qmk#15559)

* Diff reduction between ADNS9800 and PMW3360 drivers.

They are very similar devices. This (somewhat) unreadable diff is
essentially a no-op, but it makes a `vimdiff` between the 2 drivers much
more readable.

* Cleanup pwm3360 driver some more.

Remove redundant calls to spi_start() and spi_stop(), as pmw3360_write()
will already call these.
