The patch fixes the following issues in the original implementation:
1. MtrrSetting contains random value if MTRR is not supported.
2. Unconditionally access fixed MTRR on CPU that may not support
fixed MTRR.
3. The maximum number of Variable MTRR entries are initialized, while
the portion exceeding the maximum number remains uninitialized.
