[PATCH v2 1/2] fsl/corenet_generic: add a particular initialization for platform

From: Wang Dongsheng <dongsheng.wang at freescale.com>

Corenet_generic is a generic platform initialization. Those based on
the corenet_generic board maybe need a particular initialize to
enable/set some IP-Blocks. So add "Fix Generic Initialization" to solve
this kind of special cases.

 1/ Split DIU code.
 2/ make fix.c as a independent driver.
