dt-bindings: soc: ti,omap-dmm: Convert to DT schema

Browse Source 
Convert the TI OMAP Dynamic Memory Manager (DMM) dt binding
from text format to DT schema.

During conversion following changes were made:
- Move file from /bindings/arm/omap to /bindings/soc/ti/
- Make the 'ti,hwmods' property optional and mark it deprecated as it is
  no longer used, it is kept to support legacy dtbs.
- Add the missing required property 'interrupts' to example node.

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@4e000000 {
compatible = "ti,omap4-dmm";
reg = <0x4e000000 0x800>;
ti,hwmods = "dmm";
};
