CONFIG_GENERIC_GETTIMEOFDAY is a sufficient condition to verify if an
architecture implements asm/vdso/clocksource.h or not. The current
implementation wrongly assumes that the same is true for the config
option CONFIG_ARCH_CLOCKSOURCE_DATA.
This results in a series of build errors on ia64/sparc/sparc64 like this:
In file included from ./include/linux/clocksource.h:31,
from ./include/linux/clockchips.h:14,
from ./include/linux/tick.h:8,
from fs/proc/stat.c:15:
./include/vdso/clocksource.h:9:10: fatal error: asm/vdso/clocksource.h:
No such file or directory
9 | #include <asm/vdso/clocksource.h>
| ^~~~~~~~~~~~~~~~~~~~~~~~
Fix the issue removing the unneeded config condition.
