x86/hvm: use white-lists for HVM param guest accessibility checks

There are actually very few HVM parameters that a guest needs to read
and even fewer that a guest needs to write. Use white-lists to specify
those parameters and also ensre that, by default, newly introduced
parameters are not accessible.
