[PATCH 05/13] mach-snapdragon: enable BINMAN

[Sam Day via B4 Relay]

From: Sam Day <me at samcday.com>

Now that binman provides abootimg support and we've defined
configuration for it on a number of qcom devices, let's enable BINMAN
for *all* ARCH_SNAPDRAGON builds.

This is a pragmatic choice: BINMAN needs to be pulled in by an existing
Kconfig symbol so we can't just enable it in a .config fragment. Rather
than defining a new symbol that can be opted into, we just opt in
everywhere. There's plenty of prior art for ARCH_* symbols doing exactly
this.

Not necessarily all (though, I suspect, a vast majority) of qcom devices
need or can benefit from binman. Unfortunately, binman will choke if a
DEVICE_TREE= lacking the `binman{}` DT node is selected as the control
FDT. To accommodate this, we drop in a small globally-included .dtsi
fragment that defines an empty binman{} node, so that no builds are
broken.
