Log Message:
-----------
Sync patches r14005, r14011, r14012, r14021, r14022 and r14043 from main trunk.
1. Reclaim work space when the remaining space size is even not enough to
contain one header + one record.
2. Check status before reporting error status code.
3. Initialize a local work space header to be used by IsValidWorkSpace() and
InitWorkSpaceHeader() to avoid executing code(gBS->CalculateCrc32 ()) outside
SMRAM while inside SMM.
4. MdeMdeModulePkg/Xhci: Fix a wrong conditional judgment which bring assertion
with 1.0 hub.
5. MdeMdeModulePkg/Ehci: Add logic to dispatch OHCI driver first if the
companion controller is OHCI.
6. Fix the bug that the device claiming too much resource cannot be rejected by
the PciBus driver.
