The current implementation of macro L/LL/UL/ULL concatenates the input
with "L"/"LL"/"UL"/"ULL" respectively.
In the case where a macro is passed to L/LL/UL/ULL as input,
the input macro name is concatenated with, rather than expanding
the input macro and then concatenating it.
The implementation of L/LL/UL/ULL is modified to two level macro,
so as to concatenate to the expansion of a macro argument.
Change 5b33ad174a "Unify type of "cpu_idx" across PSCI module."
has modified the implementation of U() to two level macros without
changing the implementation of other macros.
