rtc: m48t59: Remove division condition with direct comparison
Replace 'year / 100' with a direct comparison 'year >= 100'
in m48t59_rtc_set_time() function. Improve the code clarity
and eliminate division overhead.
Fix the following smatch warning:
drivers/rtc/rtc-m48t59.c:135 m48t59_rtc_set_time() warn:
replace divide condition 'year / 100' with 'year >= 100'
