rb5: Add support for Qcom Robotics RB5 development kitandroid-s-beta-5

* Add new lunch target "rb5-userdebug"
* Boots android-mainline (3aa53d85a061) to UI
* ADB works
* If you are having display issues on your brand new RB5
  kit then run the following set of adb commands to update
  the lt9611uxc firmware version:
    adb wait-for-device; adb root;
    adb shell "echo 1 > /sys/bus/i2c/devices/5-002b/lt9611uxc_firmware"
  Check installer/rb5/README for more details.

+These instructions will help you flashing the prebuilt bootloader
+and AOSP images(built from sources) on rb5.
+
+First, make sure you have built the AOSP images for RB5 by
+running the rb5-userdebug lunch target.
+
+
+Boot the board into fastboot mode:
+----------------------------------
+The easiest way to boot into fastboot mode is to run something
+like "adb reboot bootloader" from the host, or
+"reboot bootloader" on the device.  However, this
+functionality may depend on the software installed on the board
+to work, so you may need to manually enter fastboot mode as
+follows.
+
+To manually enter fastboot mode:
+--------------------------------
+* To manually boot the board into fastboot mode, press DOWN arrow
+  key over serial UART console when restarting the board.
+
+                         OR
+
+* Follow the instructions here
+https://www.96boards.org/documentation/consumer/dragonboard/qualcomm-robotics-rb5/installation/board-recovery.md.html#booting-into-fastboot
+
+
+Flash the board:
+----------------
+Once the board is in fastboot mode, you can then flash bootloader
+binaries and AOSP images by running the following script from
+device/linaro/dragonboard/installer/rb5/ directory:
+
+  $ ./flash-all-aosp.sh
+
+
+Troubleshooting:
+----------------
+* If you have flashed AOSP images and you can see the boot logs
+  on Serial prompt but no UI then try updating the lt9611uxc
+  firmware version. Factory shipped RB5 has an older version of
+  lt9611uxc firmware flashed on it and it is incompatible with
+  upstream kernel. Try updating the firmware version by running
+  the following adb shell commands:
+
+  $ adb wait-for-device; adb root; adb shell "echo 1 > /sys/bus/i2c/devices/5-002b/lt9611uxc_firmware"
+
+* Make sure the USB-C cable is connected. As it has to be
+  removed to fully power the device down, it is easy to forget
+  to reconnect it!
+
+* If you cannot get the board into fastboot mode, or for some
+  reason the flash-all-aosp.sh script does not work, you can do
+  a full recovery flash of the board using the following
+  instructions.
+
+
+Recovery:
+--------
+First boot into recovery mode by follwing the recovery
+instructions from here:
+https://www.96boards.org/documentation/consumer/dragonboard/qualcomm-robotics-rb5/installation/board-recovery.md.html
+
+Then run the recovery script from the
+device/linaro/dragonboard/installer/rb5/ directory:
+
+  $ ./recovery.sh
+
+This will do a recovery flash of the ptable and bootloader
+binaries.
