Subject: [PATCH] ARM: omap2: fix omap5_realtime_timer_init definition

There is one more regression introduced by the last build fix:

arch/arm/mach-omap2/timer.c:170:6: error: attribute declaration must precede definition [-Werror,-Wignored-attributes]
void __init omap5_realtime_timer_init(void)
     ^
arch/arm/mach-omap2/common.h:118:20: note: previous definition is here
static inline void omap5_realtime_timer_init(void)
                   ^
arch/arm/mach-omap2/timer.c:170:13: error: redefinition of 'omap5_realtime_timer_init'
void __init omap5_realtime_timer_init(void)
            ^
arch/arm/mach-omap2/common.h:118:20: note: previous definition is here
static inline void omap5_realtime_timer_init(void)

Address this by removing the now obsolete #ifdefs in that file and
just building the entire file based on the flag that controls the
omap5_realtime_timer_init function declaration.

If this looks ok, I'd apply it directly on top again for the merge window.
