Add DragonBoard-410c as target board

This patch adds the dragonboard-410c as DragonBoard-410c target.

There are instructions to write image into eMMC and boot system at:
https://github.com/96boards/documentation/wiki/Dragonboard-410c-Installation-Guide-for-Linux-and-Android#flash-the-bootloader-into-on-board-emmc

v2: Rebase after merge conflict (jsmoeller)
v3: Generalize the eula script into function to be reuseable (jsmoeller)

+The BSP for $MACHINE depends on packages and firmware which are covered by an 
+End User License Agreement (EULA). To have the right to use these binaries
+in your images, you need to read and accept the following...
+
+The firmware package can contains several types
+of firmware (depending on BSP):
+
+* bootloaders: the first stage bootloaders are proprietary for this
+  board, they are included in this firmware package.
+* firmware for the power management 'companion' core: on QCOM SoC some
+  power management features are implemented in a companion core , called
+  RPM, and not on the main CPU.
+* firmware for GPU, WLAN, DSP/GPS and video codecs. These firmware are
+  used by their respective linux drivers (DRM, wlan, v4l2, .. ) and are
+  loaded on-demand by the main CPU onto the various cores on the SoC.
