Add the bindings for the Bifrost family of ARM Mali GPUs.
The Bifrost GPU architecture is similar to the Midgard family,
but with a different Shader Core & Execution Engine structures.
Bindings are based on the Midgard family bindings, but the inner
architectural changes makes it a separate family needing separate
bindings.
The Bifrost GPUs are present in a number of recent SoCs, like the
Amlogic G12A Family, and many other vendors.
The Amlogic vendor specific compatible is added to handle the
specific IP integration differences and dependencies.

+ARM Mali Bifrost GPU
+====================
+
+Required properties:
+
+- compatible :
+ * Since Mali Bifrost GPU model/revision if fully discoverable by reading
+ some determined registers, must contain the following:
+ + "arm,mali-bifrost"
+ * which must be preceded by one of the following vendor specifics:
+ + "amlogic,meson-g12a-mali"
+
+- reg : Physical base address of the device and length of the register area.
+
+- interrupts : Contains the three IRQ lines required by Mali Bifrost devices,
+ in the following defined order.
+
+- interrupt-names : Contains the names of IRQ resources in this exact defined
+ order: "job", "mmu", "gpu".
+
+Optional properties:
+
+- clocks : Phandle to clock for the Mali Bifrost device.
+
+- mali-supply : Phandle to regulator for the Mali device. Refer to
+ Documentation/devicetree/bindings/regulator/regulator.txt for details.
+
+- operating-points-v2 : Refer to Documentation/devicetree/bindings/opp/opp.txt
+ for details.
+
+- resets : Phandle of the GPU reset line.
+
+Vendor-specific bindings
+------------------------
+
+The Mali GPU is integrated very differently from one SoC to
+another. In order to accommodate those differences, you have the option
+to specify one more vendor-specific compatible, among:
+
+- "amlogic,meson-g12a-mali"
+ Required properties:
+ - resets : Should contain phandles of :
+ + GPU reset line
+ + GPU APB glue reset line
+
+Example for a Mali-G31:
+
+gpu@ffa30000 {
+ compatible = "amlogic,meson-g12a-mali", "arm,mali-bifrost";
+ reg = <0xffe40000 0x10000>;
+ interrupts = <GIC_SPI 160 IRQ_TYPE_LEVEL_HIGH>,
+ <GIC_SPI 161 IRQ_TYPE_LEVEL_HIGH>,
+ <GIC_SPI 162 IRQ_TYPE_LEVEL_HIGH>;

Is there any point in having "interrupt-names" if we're fixing the
order? Although I guess it helps match the Midgard bindings.

Should I still send a v5 to fixing this typo ? I can fix it while applying it.
