For now we can use the privilege flag to check. Stash the value to be
used later.
Put in a bunch of defines for future use when we want to have more
fine-grained detection.

When Linux runs as the root partition, the setup required for TSC page
is different. Luckily Linux also has access to the MSR based
clocksource. We can just disable the TSC page clocksource if Linux is
the root partition.

When Linux runs as the root partition, it will need to make hypercalls
which return data from the hypervisor.
Allocate pages for storing results when Linux runs as the root

2. Drop unnecessary exports.
v2:

2. Address Vitaly's comments

We will soon use the same structure to handle IO-APIC interrupts as
well. Introduce an enum to identify the source and a data structure for
IO-APIC RTE.
While at it, update pci-hyperv.c to use the enum.
No functional change.
