MtrrSetVariableMtrr() sets all the variable MTRR settings. But in fact MtrrSetAllMtrrs() is always used by callers to set all MTRR settings including the fixed and variable ones.
The patch removes the necessary API MtrrSetVariableMtrr() to simplify the MtrrLib API. There is no code in edk2 and edk2-platforms repo that calls MtrrGetVariableMtrr().
