* much of the basic initialization can now be generalized and
  re-used for all platforms
* implemented libplatform support for querying, creating and
  destroying devices
* added platform_ctx_t and platform_devctx_t distinction, to
  reflect the platform / device level
* platform_ctx_t holds the refs to the static TLKM interfaces
* platform_devctx_t contains access to dynamic files etc. available
  only after the device has been created
* ported generic modules to new TLKM interfaces
* will need some mechanism to patch-in the board-specific code
* also, will need to implement more calls, e.g., read and write:
  if mmap is available, that is always the best solution; only use
  the TLKM interface, if mmap is not possible
* most of the that code should be generic, too
