Changes since v1:
-----------------
- v1 can be viewed here: https://lore.kernel.org/linux-arm-msm/20230314210828.2049720-1-bhupesh.sharma@linaro.org/
- Addressed review comments from Konrad and fixed the board dts and also
  added a new 'qcom,qrb4210' compatible.
- Although Krzysztof provided an Ack for [PATCH 1/2] from the v1 series,
  since this series introduces the new 'qcom,qrb4210' compatible, so I
  have dropped the same for now.
 
Add an initial device tree for Qualcomm RB2 board (see [1]).
It is based on the Robotics version of the Snapdragon SM4250
Soc, i.e. QRB4210.

Currently it enables:
    - eMMC via SDHC1,
    - uSD card via SDHC2,
    - RPM regulators,
    - Debug UART (via micro USB port).

Subsequent patchset(s) will add more peripherals like USB, etc.

This patchset is dependent on the QRB4210 SocInfo patchset sent out
earlier (see [2]).

To get a successful boot run:
    
   $ cat arch/arm64/boot/Image.gz arch/arm64/boot/dts/qcom/\
    qrb4210-rb2.dtb > ./Image-adp.gz+dtb

   $ mkbootimg --kernel ./Image-adp.gz+dtb \
     --ramdisk ./some-initramfs-image.rootfs.img \
     --output ./rb2-boot.img --pagesize 4096 \
     --base 0x80000000 --cmdline 'SOME_CMDLINE'
    
   $ fastboot boot ./rb2-boot.img
