MdeModulePkg/Variable/RuntimeDxe: move MOR func. declarations to header
The MorLockInit() and SetVariableCheckHandlerMor() functions have separate
implementations for VariableRuntimeDxe (= unprivileged, unified
DXE_RUNTIME driver) and VariableSmm (= privileged, DXE_SMM back-end of the
split variable driver).
Move their declarations from "Variable.c" to "PrivilegePolymorphic.h", so
that the compiler enforce that the declarations and the definitions match.
(All C source files with the call sites and the function definitions
already include "PrivilegePolymorphic.h" via "Variable.h".)
At the same time:
- replace two typos in the MorLockInit() description:
- replace "EFI_SUCEESS" with "EFI_SUCCESS",
- replace "MOR Lock Control" with "MOR Control Lock";
- in the SetVariableCheckHandlerMor() description:
- replace @param with @param[in],
- correct the description of the Attributes parameter (suggested by Star
Zeng <star.zeng@intel.com>),
- rewrap the comment to 80 columns.
This change cleans up commit 2f6aa774fe38 ("MdeModulePkg: Add MorLock to
variable driver.", 2016-01-19).
