[PATCH 5.1 91/96] MIPS: have "plain" make calls build dtbs for selected platforms

[Greg Kroah-Hartman]

From: Cedric Hombourger <Cedric_Hombourger@xxxxxxxxxx>

commit 637dfa0fad6d91a9a709dc70549a6d20fa77f615 upstream.

scripts/package/builddeb calls "make dtbs_install" after executing
a plain make (i.e. no build targets specified). It will fail if dtbs
were not built beforehand. Match the arm64 architecture where DTBs get
built by the "all" target.
