drm: Add function to convert rect in 16.16 fixed format to regular format
Much more clear to read one function call than four lines doing this
conversion.
v7:
- function renamed
- calculating width and height before truncate
- inlined
v10:
- renamed parameters from source and destination to src and dst
to match sister functions
