Michael Brown f3ba0fb5fd [hyperv] Provide timer based on the 10MHz time reference count MSR ...

When running on AMD platforms, the legacy hardware emulation is
extremely unreliable.  In particular, the IRQ0 timer interrupt is
likely to simply stop working, resulting in a total failure of any
code that relies on timers (such as DHCP retransmission attempts).

Work around this by using the 10MHz time counter provided by Hyper-V
via an MSR.  (This timer can be tested in KVM via the command-line
option "-cpu host,hv_time".)
