[PATCH] arm/smp: Drop the macro S(x,s)

[Anshuman Khandual <anshuman.khandual@arm.com>]

Mapping between IPI type index and its string is direct without requiring
an additional offset. Hence the existing macro S(x, s) is now redundant
and can just be dropped. This also makes the code clean and simple.
