* PMW33XX drivers overhaul
This combines the PMW3389 and PM3360 drivers as they only differ in the
firmware blobs and CPI get and set functions. The following changes have
been made:
* PMW3389 now gets the same multi-sensor feature that is already available on the
PMW3360.
* Introduced a shared pmw33xx_report_t struct is now directly readable via SPI
transactions instead of individual byte-sized reads, saving multiple
copies and bitshift operations.
* pmw33(89/60)_get_report functions had unreachable branches in their motion
detection logic these have been simplied as much as possible.
* The fast firmware upload option has been removed as this becomes obsolete by
the newly introduced polled waiting functions for ChibiOS polled waiting
* PMW33(60/89)_SPI_LSBFIRST and PMW33(60/89)_SPI_MODE config options
have been removed as they don't need to be configurable.
* All PMW3389 and PMW3360 defines have been unified to a PMW33XX prefix
to reduce code duplication and make the defines interchangeable
* Adjust keyboards to PMW33XX naming scheme
* 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.
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.
