There is no reliable way to extract the CPU MHz from the numbers here. However, it
is possible that this CPU has a known fixed speed (set by either the manufacturer
or the board design). Check the relevant doco.

For example, this doco (is this your phone?)

says "400/500 MHz", so I will assume the "BogoMIPS: 199.47" suggests 400MHz.
