ARM: 8487/1: Remove IPI_CALL_FUNC_SINGLE
Since 9a46ad6d6df3 ("smp: make smp_call_function_many() use logic
similar to smp_call_function_single()"), the core IPI handling
has been simplified, and generic_smp_call_function_interrupt is
now the same as generic_smp_call_function_single_interrupt.
This means that one of IPI_CALL_FUNC and IPI_CALL_FUNC_SINGLE has
become redundant. We can then safely drop IPI_CALL_FUNC_SINGLE,
and use only IPI_CALL_FUNC.
This has the advantage of reducing the number of SGI IDs we're using
(a fairly scarse resource).
Tested on a dual A7 board.
