Add function to determine virtual FD support

iRMC dropped support of virtual floppy disk at specific
iRMC firmware version.

iRMC S4 supports virtual FD till version 9.21F and deprecates
it from version 9.62F
iRMC S5 supports virtual FD till version 1.25P and deprecates
it from version 1.60P

This commit adds functions which determine whether iRMC supports
virtual floppy disk based on iRMC firmware version.
