Since we have a common x86 quirk that provides an exported variable,
use it instead of local DMI table match.

Note, arch/x86/kernel/quirks.c::early_platform_detect_quirk() prints
the detected platform.

Are we going to convert all the other platforms to using a variable too?

It makes sense to ones that have spread quirks over the kernel, like Apple.
