Synch up OMI and MCA frequencies
There is an intrinsic link between ATTR_FREQ_MCA_MHZ and
ATTR_FREQ_OMI_MHZ and ATTR_MC_PLL_BUCKET.
-ATTR_MC_PLL_BUCKET will be read-only, platforms will return the
value based on ATTR_FREQ_OMI_MHZ.
-ATTR_FREQ_MCA_MHZ will be read-only (again), platforms will return
the value based on ATTR_FREQ_OMI_MHZ.
-ATTR_FREQ_OMI_MHZ will be writeable, defaulted by mrw/config file,
written by mss_freq_system.
-OMI_PLL_FREQ_LIST was be expanded to include the value of
ATTR_FREQ_MCA_MHZ. Platforms will use ATTR_FREQ_OMI_MHZ (and VCO)
as the key into OMI_PLL_FREQ_LIST to determine the value of
ATTR_MC_PLL_BUCKET and ATTR_FREQ_MCA_MHZ
