[PATCH 1/2] Revert "domain: add tsc.on_reboot element"

[Michal Privoznik <mprivozn@xxxxxxxxxx>]

This reverts commit 150540394ddaa515f6857616a2bcf792748f162c.

Turns out, this feature is not needed and QEMU will fix TSC
without any intervention from outside.

    ``frequency``
       The ``frequency`` attribute is an unsigned integer specifying the
       frequency at which ``name="tsc"`` runs.
-   ``on_reboot``
-      The ``on_reboot`` attribute controls how the ``name="tsc"`` timer behaves
-      when the VM is reset, and can be "default", "clear" or "keep". The reset
-      behavior of other timers is hardcoded, and depends on the type of timer.
    ``mode``
       The ``mode`` attribute controls how the ``name="tsc"`` timer is managed,
       and can be "auto", "native", "emulate", "paravirt", or "smpsafe". Other
