qdutils: Retrieve MDP revision and pipes information from driver.

Browse Source 
Userspace can retrieve MDP revision number and number of different
types of MDP pipes (RGB,VG,DMA) information from driver. Add target
specific flag as previous MDP versions do not provide this support.

- Make use of this information while maintaining PipeBook.
- Move PipeBook related functions from overlay utils to PipeBook.
