Subject: [PATCH v7 44/49] x86/resctrl: Relax some asm #includes

From: Dave Martin <Dave.Martin@....com>

checkpatch.pl identifies some direct #includes of asm headers that
can be satisfied by including the corresponding <linux/...> header
instead.

Fix them.

No intentional functional change.

Changes since v6:
 * This patch is new.

Changes since v2:
 * asm->linux for resctrl.h moved into an earlier patch.
