exynos4210_rtc: Use ptimer_free() in the finalize function to avoid memleaks

When running device-introspect-test, a memory leak occurred in the
exynos4210_rtc_init function, so use ptimer_free() in the finalize function to
avoid it.

ASAN shows memory leak stack:

Indirect leak of 96 byte(s) in 1 object(s) allocated from:
    #0 0xffffab97e1f0 in __interceptor_calloc (/lib64/libasan.so.5+0xee1f0)
