Subject: [edk2] [PATCH v2] SecurityPkg: Fix potential bug in Security Boot dxe.
v2: update hash value in SecureBootConfig.vfr to keep them consistent with macro definition in SecureBootConfigImpl.h
since we removed the sha-1 definition in Hash table and related macro, but the macro definition HashAlg index may be value 4 which is exceed the range of the Hash table array.
