Add Dynamic Memory Manager (DMM) bindings for OMAP4 and OMAP5 devices. DMM
only requires address and irq information.
Add documentation for the DMM bindings.

+OMAP Dynamic Memory Manager (DMM) bindings
+
+The dynamic memory manager (DMM) is a module located immediately in front of
the
+SDRAM controllers (called EMIFs on OMAP). DMM manages various aspects of memory
+accesses such as priority generation amongst initiators, configuration of SDRAM
+interleaving, optimizing transfer of 2D block objects, and provide MMU-like
page
+translation for initiators which need contiguous dma bus addresses.
+
+Required properties:
+- compatible: Should contain ti,omap4-dmm for OMAP4 family
+ Should contain ti,omap5-dmm for OMAP5 and DRA7x family
+- reg: Contains DMM register address range (base address and length)
+- interrupts: Should contain an interrupt-specifier for DMM_IRQ.
+- ti,hwmods: Name of the hwmod associated to DMM, which is typically dmm
+
+Example:
+
+dmm@4e00 {
+ compatible = ti,omap4-dmm;
+ reg = 0x4e00 0x800;
+ ti,hwmods = dmm;
+};
