drm/mga: drop dependency on drm_os_linux.h
Opencode all macros used from the deprecated drm_os_linux.h header file.
The DRM_WAIT_ON used 3 * HZ as timeout.
This was translated to 3000 msec.
The return value of mga_driver_fence_wait() was not
used, so make it return void to simplify code a bit.
v2:
- fixed timeout to 3000 msec (original value was 3 * Hz)
- drop unused return value from mga_driver_fence_wait()
