rtc: max77686: Use ffs() to calculate tm_wday
max77686_rtc_calculate_wday() is used to calculate the day of the week to be filled in struct rtc_time but that function only calculates the number of bits shifted. So the ffs() function can be used to find the first bit set instead of a special function.
