[PATCH] [v2] ARM: omap2: fix omap5_realtime_timer_init definition

[Arnd Bergmann]

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)

As it turns out, the CONFIG_SOC_HAS_REALTIME_COUNTER option
should never be disabled for OMAP5 as we realy on this to initialize
the clocks and the timer. Just remove it here and make it the default.

Removing the guard around the set_cntfreq() definition, I noticed that
this is not properly namespaced, so fix that as well.

I'll let this run randconfig builds overnight to be sure it doesn't
cause another regression.
