Please add:
#include <linux/bitops.h>
... immediately before the includes below; it's needed to ensure that
BIT() is defined in all cases. Previously we were relying on implicit
header includes, which is not good practice.

If we're going to expose these in a header, it would be better to rename
them to something that makes their usage/meaning clear. These should
probably be ARCH_TIMER_TYPE_{CP15,MEM}.
I guess this can wait for subsequent cleanup.

Please rename this to arch_timer_ppi_nr (updating the single user in
drivers/clocksource/arm_arch_timer.c). That'll avoid the potential for
name clashes in files this happens to get included in (potentially
transitively via other headers).
With those changes (regardless of the ARCH_TIMER_TYPE_* bits):
