[Xen-devel] [PATCH v6 15/16] x86/init: disable pnpbios for X86_SUBARCH_INTEL_MID

["Luis R. Rodriguez" <mcgrof@xxxxxxxxxx>]

As per hpa Intel MID platforms can also disable pnpbios [0].

As per 0-day, this bumps the vmlinux size using i386-tinyconfig as
follows:

TOTAL   TEXT   init.text   x86_early_init_platform_quirks()
-8      -8     -8          -8

[0] http://lkml.kernel.org/r/5702B5C2.7070101@xxxxxxxxx

v6: add 0-day size impact
