[PATCH 0637/1285] Replace numeric parameter like 0444 with macro

[Baole Ni <baolex.ni@intel.com>]

I find that the developers often just specified the numeric value
when calling a macro which is defined with a parameter for access permission.
As we know, these numeric value for access permission have had the corresponding macro,
and that using macro can improve the robustness and readability of the code,
thus, I suggest replacing the numeric parameter with the macro.
