Subject: [PATCH AUTOSEL 4.19 02/17] ARC: [plat-eznps]: Restrict to CONFIG_ISA_ARCOMPACT

From: Vineet Gupta <vgupta@...opsys.com>

[ Upstream commit 799587d5731db9dcdafaac4002463aa7d9cd6cf7 ]

Elide invalid configuration EZNPS + ARCv2, triggered by a
make allyesconfig build.

Granted the root cause is in source code (asm/barrier.h) where we check
for ARCv2 before PLAT_EZNPS, but it is better to avoid such combinations
at onset rather then baking subtle nuances into code.
