From: Fabio Estevam fabio.estevam@freescale.com
The original definition of IPU_CTRL_BASE_ADDR does match the value stated in the MX53 Reference Manual.
However, if using such value the IPU driver hangs when trying to access the IPU registers.
Looking for this definition in Freescale U-boot version shows that it is set as 0.
Set it as 0 here as well, so that we can have a working IPU driver for mx53.
