kvm FSB clock is 1GHz, not 100 MHz. Timings are off by factor 10.
Fix all affected build configurations. Not changed: Microvm and
Cloudhw (they have already have the correct value), and Xen (has
no fixed frequency, the PCD is configured at runtime by platform
initialization code).

Fixes: c37cbc030d96 ("OvmfPkg: Switch timer in build time for OvmfPkg")
Cc'ing gaoliming.

This fixes a regression and should go into 220205

thanks,
