Subject: [PATCH 0/2] arm64: dts: qcom: Add Qualcomm RB2 board dts

Add an initial device tree for Qualcomm RB2 board (see [1]).
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.

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
