For different chips, different types and numbers of components are
configured in the MDP3 to achieve the desired application, which will
cause ID compatibility problems in the same driver.

Subdivide the component ID into two kinds:
	1. public_id (compatible with other chips)
	2. inner_id (what the current chip actually owns)

In addition, the chip configuration related structures of MDP3 components
are integrated into specific file.
