Reuse -cpu,tsc-frequency= to get user wanted tsc frequency and pass it
to KVM_TDX_INIT_VM.
Besides, sanity check the tsc frequency to be in the legal range and
legal granularity (required by SEAM module).

Should this be 25KHz instead of 25MHz?
No. It equals to
(evn->tsc_khz * 1000) % (25 * 1000 * 1000)
