Add support for CLAA07LC0ACW LCD that connects to the mx53loco board.

Configure the board to show the Linux logo on the LCD.

Also increase the size of CONFIG_SYS_MALLOC_LEN variable to take into account the framebuffer usage.

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.

Apart of the fact that it works, this chane appears really strange to me. Maybe now it is not writing anymore in ipu, and the default values are ok for mx53. It seems more a MX53 related issu in IPU3 driver, and this change maybe hides the real problem. Do you have any additional information to make this modification against the official Freescale's reference manual ?
