[PATCH] arm64: dts: Add symlinks for cros-ec-keyboard and cros-ec-sbs

[PATCH] arm64: dts: Add symlinks for cros-ec-keyboard and cros-ec-sbs

[Douglas Anderson]

We'd like to be able to use the cros-ec-keyboard.dtsi and
cros-ec-sbs.dtsi snippets for arm64 devices.  Currently those files live
in the arm/boot/dts directory.

Let's follow the convention set by commit 8ee57b8182c4 ("ARM64: dts:
vexpress: Use a symlink to vexpress-v2m-rs1.dtsi from arch=arm") and use
a symlink.  Note that in this case we put the files in a new
"include/common" directory since these snippets may need to be
referenced by dts files in many different subdirectories.

Note that, as of right now, there are no users of this.  However, given
development happening it is almost 100% certain that users will arrive
soon.  If we need to wait for the first user before landing this we can
leave this on the back burner.  If it's OK to have no users (yet), let's
land.

This may not fit your definition of "soon", but I'm looking to start
using these files in arch/arm64/. I'll probably carry along this patch
and resend when I'm ready, but it'd be just as well if you'd merge it
now (or express a preference for a different directory structure).

Till now I was expecting to just pick up this patch as well once the first 
(rk3399-)users arrived. But of course it could also be picked up separately.

I'm also running with this on my rk3399-gru and it sucessfully enables the 
cros-ec keyboard :-) ,so if anyone picks it up before me they can add
