Convert s5p-mfc bindings to DT schema format using json-schema.

Signed-off-by: Aakarsh Jain <aakarsh.jain@samsung.com>
---
changes since v6:
kept hw properties for Exynos3250 and Exynos4
under different if:then condition.

changes since v5:
kept compatible strings under enum
sorted compatible strings
added iommu maxItems:2
Added indentation with 4 spaces in dts example

changes since v4:
Removed items from oneOf section
dropped black line
defined the iommus names items as
items:
-const left
-const right

changes since v3:
fixed dt-schema warnings and errors while running make dtbs_check and make dt_binding_check for ARMv7
Since, obsolete properties are not part of dt-node so we are not including these properties in dt-schema.

changes since v2:
changed Commit message from Adds to Convert
Removed text "This file has moved to samsung,s5p-mfc.yaml" from s5p-mfc.txt
fixed dt-schema warnings and errors while running make dtbs_check and make dt_binding_check

changes since v1:
fixed dt-schema warnings and errors while running make dtbs_check and make dt_binding_check
Removed description.
Listed items.
Added allOf:if:then for restricting two items to specific compatible

This is a friendly reminder during the review process.

It looks like you received a tag and forgot to add it.

If you do not know the process, here is a short explanation:
Please add Acked-by/Reviewed-by/Tested-by tags when posting new
versions. However, there's no need to repost patches *only* to add the
tags. The upstream maintainer will do that for acks received on the
version they apply.

https://elixir.bootlin.com/linux/v5.17/source/Documentation/process/submitting-patches.rst#L540

If a tag was not added on purpose, please state why and what changed.

Hi Krzysztof,

I don’t see this patch in linux-next. It's been more than a month now. 
Please let me know if any other changes required.


Thanks,

Thanks for your review.
The question was more on, if you will pick up this patch via your tree or this will go via Rob's or Media tree.
I will prefer if this goes via your tree.

Generic recommendation is that all device-related bindings go via their
subsystem, so in this case via media tree. I see in patchwork it is
still in new state, so maybe was forgotten. OK, let me grab it.

-Multi Format Codec (MFC) is the IP present in Samsung SoCs which

-The MFC device driver is a v4l2 driver which can encode/decode
-video raw/elementary streams and has support for all popular
-video codecs.
-
-Required properties:
-  - compatible : value should be either one among the following
-	(a) "samsung,mfc-v5" for MFC v5 present in Exynos4 SoCs
-	(b) "samsung,mfc-v6" for MFC v6 present in Exynos5 SoCs

-
-  - reg : Physical base address of the IP registers and length of memory

-
-  - interrupts : MFC interrupt number to the CPU.
-  - clocks : from common clock binding: handle to mfc clock.
-  - clock-names : from common clock binding: must contain "mfc",

-Optional properties:
-  - power-domains : power-domain property defined with a phandle
-			   to respective power domain.
-  - memory-region : from reserved memory binding: phandles to two reserved
-	memory regions, first is for "left" mfc memory bus interfaces,
-	second if for the "right" mfc memory bus, used when no SYSMMU
-	support is available; used only by MFC v5 present in Exynos4 SoCs
-
-Obsolete properties:
-  - samsung,mfc-r, samsung,mfc-l : support removed, please use memory-region

-Example:
