[PATCH] ARM: dts: add SolidRun SolidSense support

[Russell King <rmk+kernel@armlinux.org.uk>]

Add support for the SolidRun SolidSense platform, which is a
Hummingboard2 with a daughter card with two Nordic software defined
radios and a couple of bi-color LEDs.

Signed-off-by: Russell King <rmk+kernel@armlinux.org.uk>

Patch created before I joined Oracle, so I'm leaving out the "(Oracle)"
suffix I have been adding to both the authorship and sign-off.
