dt-bindings: Consolidate SRAM bindings from all vendors
SRAM bindings for various SoCs, using the mmio-sram genalloc API, are spread over different places - per SoC vendor. Since all of these are quite similar (they depend on mmio-sram) move them to a common place.

-Generic on-chip SRAM
-
-Simple IO memory regions to be managed by the genalloc API.
-
-Required properties:
-
-- compatible : mmio-sram
-
-- reg : SRAM iomem address range
-
-Reserving sram areas:
----------------------
-
-Each child of the sram node specifies a region of reserved memory. Each
-child node should use a 'reg' property to specify a specific range of
-reserved memory.
-
-Following the generic-names recommended practice, node names should
-reflect the purpose of the node. Unit address (@<address>) should be
-appended to the name.
-
-Required properties in the sram node:
-
-- #address-cells, #size-cells : should use the same values as the root node
-- ranges : standard definition, should translate from local addresses
- within the sram to bus addresses
-
-Required properties in the area nodes:
-
-- reg : iomem address range, relative to the SRAM range
-
-Optional properties in the area nodes:
-
-- compatible : standard definition, should contain a vendor specific string
- in the form <vendor>,[<device>-]<usage>
-- pool : indicates that the particular reserved SRAM area is addressable
- and in use by another device or devices
-- export : indicates that the reserved SRAM area may be accessed outside
- of the kernel, e.g. by bootloader or userspace
-- label : the name for the reserved partition, if omitted, the label
- is taken from the node name excluding the unit address.
-
-Example:
-
-sram: sram@5c000000 {
- compatible = "mmio-sram";
- reg = <0x5c000000 0x40000>; /* 256 KiB SRAM at address 0x5c000000 */
-
- #adress-cells = <1>;
- #size-cells = <1>;
- ranges = <0 0x5c000000 0x40000>;
-
- smp-sram@100 {
- compatible = "socvendor,smp-sram";
- reg = <0x100 0x50>;
- };
-
- device-sram@1000 {
- reg = <0x1000 0x1000>;
- pool;
- };
-
- exported@20000 {
- reg = <0x20000 0x20000>;
- export;
- };
-};
