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.

-==============
-
-This layer provides that evaluation board is mounted ARM SoCs of Renesas
-Electronics, called the R-Car Generation 3. Currently, this supports
-board and the SoCs of the following:
-     - Board: Salvator-X / SoC: R8A7795 (R-Car H3), R8A7796 (R-Car M3), R8A77965 (R-Car M3N)
-     - Board: R-Car Starter Kit premier(H3ULCB) / SoC: R8A7795 (R-Car H3)
-     - Board: R-Car Starter Kit pro(M3ULCB) / SoC: R8A7796 (R-Car M3)
-     - Board: Ebisu / SoC: R8A77990 (R-Car E3)
-
-Patches
-=======
-
-Please submit any patches for this layer to: takamitsu.honda.pv@renesas.com
-Please see the MAINTAINERS file for more details.

-Dependencies
-============
-
-This layer depends on:
-
-    URI: git://git.yoctoproject.org/poky
-    layers: meta, meta-yocto, meta-yocto-bsp
-    branch: rocko
-
-    URI: git://github.com/renesas-rcar/meta-renesas
-    layers: meta-rcar-gen3
-    branch: rocko
-
-    URI: git://git.linaro.org/openembedded/meta-linaro.git
-    layers: meta-optee

-    layers: meta-oe
-    branch: rocko

-Build Instructions
-==================
-
-The following instructions require a Poky installation (or equivalent).
-
-Initialize a build using the 'oe-init-build-env' script in Poky. e.g.:
-
-    $ source poky/oe-init-build-env
-
-After that, initialized configure bblayers.conf by adding meta-rcar-gen3 layer. e.g.:
-
-    BBLAYERS ?= " \
-        <path to layer>/poky/meta \
-        <path to layer>/poky/meta-yocto \
-        <path to layer>/poky/meta-yocto-bsp \
-        <path to layer>/meta-renesas/meta-rcar-gen3 \
-        <path to layer>/meta-linaro/meta-optee \
-        <path to layer>/meta-openembedded/meta-oe \
-    "
-
-To build a specific target BSP, configure the associated machine in local.conf:
-
-    MACHINE ??= "<supported board name>"
-
-Select the SOC
-
-    For H3: r8a7795
-    SOC_FAMILY = "r8a7795"
-
-    For M3: r8a7796
-    SOC_FAMILY = "r8a7796"
-
-    For M3N: r8a77965
-    SOC_FAMILY = "r8a77965"
-
-    For E3: r8a77990
-    SOC_FAMILY = "r8a77990"
-    Already added in machine config: ebisu.conf
-
-Configure for systemd init in local.conf:
-
-    DISTRO_FEATURES_append = " systemd"
-    VIRTUAL-RUNTIME_init_manager = "systemd"
-
-Configure for ivi-shell and ivi-extension
-
-    DISTRO_FEATURES_append = " ivi-shell"
-
-Configure for USB 3.0
-
-    MACHINE_FEATURES_append = " usb3"
-
-Enable tuning support for Capacity Aware migration Strategy (CAS)
-
-    MACHINE_FEATURES_append = " cas"
-
-Build the target file system image using bitbake:
-
-    $ bitbake core-image-minimal
-
-After completing the images for the target machine will be available in the output
-directory 'tmp/deploy/images/<supported board name>'.
-
-Images generated:
-    * Image (generic Linux Kernel binary image file)
-    * Image-<machine name>.dtb (DTB for target machine)
-    * core-image-minimal-<machine name>.tar.bz2 (rootfs tar+bzip2)
-    * core-image-minimal-<machine name>.ext4  (rootfs ext4 format)
-
-Build Instructions for SDK
-==========================
-This may be changed in the near feature. These instructions are tentative.
-
-Should define the staticdev in SDK image feature for installing the static libs
-to SDK in local.conf.
-
-    SDKIMAGE_FEATURES_append = " staticdev-pkgs"
-
-Use bitbake -c populate_sdk for generating the toolchain SDK:
-For 64-bit target SDK (aarch64):
-
-    $ bitbake core-image-minimal -c populate_sdk
-
-The SDK can be found in the output directory 'tmp/deploy/sdk'
-    * poky-glibc-x86_64-core-image-minimal-aarch64-toolchain-x.x.sh
-
-Usage of toolchain SDK:
-Install the SDK to the default: /opt/poky/x.x
-For 64-bit target SDK:
-
-    $ sh poky-glibc-x86_64-core-image-minimal-aarch64-toolchain-x.x.sh
-
-For 64-bit application use environment script in /opt/poky/x.x
-
-    $ source /opt/poky/x.x/environment-setup-aarch64-poky-linux
