The bulk of this change was tightly coupled and needed to be deleted in one pass. Some of the smaller changes were things that broke as a result of the initial purge and subsequently fixed by further eradicating unnecessary platform differences. Finally, I deleted any dead code I came across in the related files I touched while going through everything.
- DriverFramework (src/lib/DriverFramework submodule) completely removed
- added dspal submodule in qurt platform (was brought in via DriverFramework)
- all df wrapper drivers removed
- all boards using df wrapper drivers updated to use in tree equivalents
- unused empty arch/board.h on posix and qurt removed
- unused IOCTLs removed (pub block, priv, etc)
- Integrator delete methods only used from df wrapper drivers
- commander: sensor calibration use "NuttX version" everywhere for now
- sensors: update to px4_{open, read, close} instead of DevMgr wrapper (adc open for analog differential pressure)
- battery_status: update to px4_{open, read, close} instead of DevMgr wrapper (adc open for analog differential pressure)
- cdev cleanup conflicting typedefs and names with actual OS (pollevent_t, etc)
- load_mon and top remove from linux boards (unused)
- delete unused PX4_MAIN_FUNCTION
- delete unused getreg32 macro
- delete unused SIOCDEVPRIVATE define
- named each platform tasks consistently
- posix list_devices and list_topics removed (list_files now shows all virtual files)
