dt-bindings: mmc: synopsys-dw-mshc: integrate Altera and Imagination

Browse Source 
The bindings for Altera and Imagination extensions are the same as for
the original Synopsys Designware Mobile Storage Host Controller.
Integrate them into Synopsys bindings to have dtschema coverage.

* Imagination specific extensions to the Synopsys Designware Mobile Storage
Host Controller
The Synopsys designware mobile storage host controller is used to interface
a SoC with storage medium such as eMMC or SD/MMC cards. This file documents
differences between the core Synopsys dw mshc controller properties described
by synopsys-dw-mshc.txt and the properties used by the Imagination specific
extensions to the Synopsys Designware Mobile Storage Host Controller.
Required Properties:
* compatible: should be
- "img,pistachio-dw-mshc": for Pistachio SoCs
Example:
mmc@18142000 {
compatible = "img,pistachio-dw-mshc";
reg = <0x18142000 0x400>;
interrupts = <GIC_SHARED 39 IRQ_TYPE_LEVEL_HIGH>;
clocks = <&system_clk>, <&sdhost_clk>;
clock-names = "biu", "ciu";
fifo-depth = <0x20>;
bus-width = <4>;
disable-wp;
