Instead of using generic CONFIG_HVM option switch to a bit more specific

altp2m routines, so that it can be disabled completely in the build.

Altp2m is not VMX-specific. It's just no-one has wired it up on AMD, or
accepted the long-outstanding ARM patchset where it was made to work.
If you want to compile it, you probably want CONFIG_ALTP2M.
However, it's not even x86 specific. See the uses in common/monitor.c
As Andrew said, it is not VMX specific so shouldn't be tied to that.
Adding a CONFIG_ALTP2M would be OK.
understood. I shall go with CONFIG_ALTP2M option then. Thanks for
clarification!
