MdeModulePkg: Add bRefClkFreq card attribute programming support
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 Others: Reserved Cc: Wu Hao A <hao.a.wu@intel.com> Cc: Albecki Mateusz <mateusz.albecki@intel.com> Cc: Liming Gao <gaoliming@byosoft.com.cn> Cc: Zhiguang Liu <zhiguang.liu@intel.com> Signed-off-by: Purna Chandra Rao Bandaru <purna.chandra.rao.bandaru@intel.com> Reviewed-by: Hao A Wu <hao.a.wu@intel.com>
