[PATCH] ARM: enable ARM_HAS_SG_CHAIN for multiplatform

Enable ARM_HAS_SG_CHAIN for all multiplatform targets, it makes sense
to enable on all "modern" platforms; downsides are limited for platforms
that don't need it.

I'll apply this to next/soc in lack of better places. I did a build+boot
test across my set of machines earlier today and it didn't seem to cause
any problems.
