PATCH 1/2 KVM: PPC: Only use QPRs when available

BookE KVM doesn't know about QPRs, so let's not try to access then.

This fixes a build error on BookE KVM.

PATCH 2/2 KVM: PPC: Don't export Book3S symbols on BookE

Book3S knows how to convert floats to doubles and vice versa. BookE doesn't. So let's make sure we don't export them on BookE.

This fixes a link error on BookE with CONFIG_KVM=y.
