Should be PcdGetBool(). The only time FixedPcdGetxxx() is required is
if the PCD value is being used to initialize a struct where the value
is needed at build time. This allows the PCD type to be flexible and
can be set in platform scope in the DSC file.

Which PCD section is this in? This PCD should support all PCD types so
it can allow Fixed or Patchable or Dynmaic PCD types.
