[PATCH 4/9] x86/init: make ebda depend on PC subarch

["Luis R. Rodriguez" <mcgrof@kernel.org>]

This lets us remove its use of paravirt_enabled(). The
other subarchs are not needed here given that on 32-bit
there is a switch already that negates access to this
code on X86_SUBARCH_INTEL_MID, and X86_SUBARCH_CE4100.
Both lguest and Xen had paravirt_enabled so that
excludes them.
