REF: https://bugzilla.tianocore.org/show_bug.cgi?id=3851
When the UFS card comes out of Manufacturer, bRefClkFreq attribute is set
to 1h on the UFS card as per the Manufacturer Default Value
specified by the spec JESD220*. However, depends on the UFS host system
environment, it need to be set to the correct value.
Reference Clock Frequency value
0h:19.2 MHz
1h: 26 MHz
2h: 38.4 MHz
3h: Obsolete
