Show option->text of BIOS knob in Redfish response.

GET on /redfish/v1/Registries/BiosAttributeRegistry/BiosAttributeRegistry/
shows list of Attributes under RegistryEntries. Each attribute
corresponds to a knob in BIOS.

If knob in BIOS is of type Enumeration, it will have 'option' with
'text' and 'value'. This text should be mapped to
attribute->Value->ValueDisplayName.

Code changes are made for the same.

Tested
