Convert the device tree bindings for the Altera Stratix10 SoCFPGA ECC
Manager from text to yaml.
Signed-off-by: Matthew Gerlach <matthew.gerlach@altera.com>

v2:
- Fix $id: path.
- Remove unneeded '|'.
- Move vendor properties last (but before child nodes).
- Add appropriate blank lines.
- Don't break ABI.
- Avoid changing existing DTSI and DTS.

-Stratix10 SoCFPGA ECC Manager (ARM64)
-The Stratix10 SoC ECC Manager handles the IRQs for each peripheral
-in a shared register similar to the Arria10. However, Stratix10 ECC
-requires access to registers that can only be read from Secure Monitor
-with SMC calls. Therefore the device tree is slightly different. Note
-that only 1 interrupt is sent in Stratix10 because the double bit errors
-are treated as SErrors in ARM64 instead of IRQs in ARM32.
-
-Required Properties:
-- compatible : Should be "altr,socfpga-s10-ecc-manager"
-- altr,sysgr-syscon : phandle to Stratix10 System Manager Block
- containing the ECC manager registers.
-- interrupts : Should be single bit error interrupt.
-- interrupt-controller : boolean indicator that ECC Manager is an interrupt controller
-- #interrupt-cells : must be set to 2.
-- #address-cells: must be 1
-- #size-cells: must be 1
-- ranges : standard definition, should translate from local addresses
-
-Subcomponents:

-Required Properties:
-- compatible : Should be "altr,sdram-edac-s10"
-- interrupts : Should be single bit error interrupt.
-
-On-Chip RAM ECC
-Required Properties:
-- compatible : Should be "altr,socfpga-s10-ocram-ecc"
-- reg : Address and size for ECC block registers.
-- altr,ecc-parent : phandle to parent OCRAM node.
-- interrupts : Should be single bit error interrupt.
-
-Ethernet FIFO ECC
-Required Properties:
-- compatible : Should be "altr,socfpga-s10-eth-mac-ecc"
-- reg : Address and size for ECC block registers.
-- altr,ecc-parent : phandle to parent Ethernet node.
-- interrupts : Should be single bit error interrupt.
-
-NAND FIFO ECC
-Required Properties:
-- compatible : Should be "altr,socfpga-s10-nand-ecc"
-- reg : Address and size for ECC block registers.
-- altr,ecc-parent : phandle to parent NAND node.
-- interrupts : Should be single bit error interrupt.
-
-DMA FIFO ECC
-Required Properties:
-- compatible : Should be "altr,socfpga-s10-dma-ecc"
-- reg : Address and size for ECC block registers.
-- altr,ecc-parent : phandle to parent DMA node.
-- interrupts : Should be single bit error interrupt.
-
-USB FIFO ECC
-Required Properties:
-- compatible : Should be "altr,socfpga-s10-usb-ecc"
-- reg : Address and size for ECC block registers.
-- altr,ecc-parent : phandle to parent USB node.
-- interrupts : Should be single bit error interrupt.
-
-SDMMC FIFO ECC
-Required Properties:
-- compatible : Should be "altr,socfpga-s10-sdmmc-ecc"
-- reg : Address and size for ECC block registers.
-- altr,ecc-parent : phandle to parent SD/MMC node.
-- interrupts : Should be single bit error interrupt for port A
- and then single bit error interrupt for port B.

This doesn't work for socfpga_arria10.dtsi. You need:

- items:

- const: altr,socfpga-a10-ecc-manager
- const: altr,socfpga-a10-ecc-manager
Make sure the other compatibles pass validation too.
