cr50_rma_open: add support for checking prepvt and prod versions

Browse Source 
RMA support through the cr50 console is only a part images starting with
0.4.5. Check that the prepvt version is greater than or equal to 0.4.5.
Versions 0.4.4 are greater than the prod version 0.3.3, but you can't
use it to do RMA open through the console. It can only be done through
the AP.
