[PATCH v5 1/2] ARM: EXYNOS4: Change System MMU device definition

From: KyongHo Cho
Date: Wed Oct 12 2011 - 05:25:29 EST

This patch contains a lot of changes of System MMU device definition.

1. Removed sysmmu_ips enumeration that are definitions of ID of System MMU
Instead, a System MMU device descriptor must be bound with a device
descriptor that needs System MMU in machine initialization.
2. Removed MDMA that is included in LCD0 block because it is not used
anymore. Use MDMA in TOP block.
3. Changed System MMU definitions of platform device. It is not an array
anymore.
