[PATCH V3 07/17] MdeModulePkg Variable: type case VolatileBase to UINTN directly

[Star Zeng <star.zeng@intel.com>]

Simplify
((UINTN) ((UINT8 *) VolatileBase + VolatileBase->Size))
to
((UINTN) VolatileBase + VolatileBase->Size)

This patch prepares for adding emulated variable NV mode
support in VariableRuntimeDxe.
