rcar-gen3: README: Use Markdown formatting

This commit edits README files to use Markdown formatting.
There are also some modifications:

- Removed dependency on meta-renesas itself in
meta-rcar-gen3/README.md and meta-rcar-gen3/README.linaro
- Added E3 SoC information to meta-rcar-gen3/README.md
- Replaced core-image-x11 by core-image-minimal in README.md,
this image is not maintained.
