perf/amlogic: Remove unused header inclusions of <linux/version.h>

According to the "Abaci Robot":

 | ./drivers/perf/amlogic/meson_g12_ddr_pmu.c:15 linux/version.h not needed.
 | ./drivers/perf/amlogic/meson_ddr_pmu_core.c: 19 linux/version.h not needed.

So drop the unnecessary #include directives.
