Subject: x86: early_quirks: fix build
From: Andrew Morton <akpm@linux-foundation.org>

With CONFIG_ACPI=n:

arch/x86/kernel/setup_64.c: In function 'setup_arch':
arch/x86/kernel/setup_64.c:420: error: implicit declaration of function 'early_quirks'

because the early_quirks() declaraion is inside an ACPI header file.

Move it out of there and into include/asm-x86/pci.h and clean a few related
things up.
