Simon Wright 87cd0d4165 Add PMW3901 (flow) sensor support (2). (#348) ...

* Added PMW3901 (flow) sensor support.
Includes general-purpose check for whether this SPI port is clocked.

  * components/src/motion/pmw3901/pmw3901.ads: new.
  * components/src/motion/pmw3901/pmw3901.adb: new.

  * components/src/motion/pmw3901/pmw3901-is_clocked.adb: new. The
      check for the associated SPI port being clocked is implemented
      as a separate because it really belongs in the Device package.

* PMW3901 driver no longer depends on STM32.

  * components/src/motion/pmw3901/pmw3901.ads: remove dependency on
      STM32, replace by HAL equivalent.
    (Initialize): replace precondition using Is_Clocked to 'not
      Is_Initialized'.
    (Is_Clocked): removed.
  * components/src/motion/pmw3901/pmw3901.adb: likewise.
  * components/src/motion/pmw3901/pmw3901-is_clocked.adb: removed.

* PMW3901 copyright/clarity updates.

  * components/src/motion/pmw3901/pmw3901.adb: Updated copyright
      notice, as requested.
  * components/src/motion/pmw3901/pmw3901.ads: Likewise.
    (Motion's rep spec): moved to private part, to reduce clutter.
