SBE Update Support for Adjusted Nest Frequency

This commit adds a check in istep 8.1 to see if the SBE Seeproms are
programmed with the same NEST_FREQ_MHZ attribute value that the system is
currently running at.  If necessary, it will update the SBE Seeproms in this
step which might result in a re-IPL.
