drivers/rtc/class.c: initialize rtc name early
In some error cases RTC name is used before it is initialized: rtc-rs5c372 0-0032: clock needs to be set rtc-rs5c372 0-0032: rs5c372b found, 24hr, driver version 0.6 rtc (null): read_time: fail to read rtc-rs5c372 0-0032: rtc core: registered rtc-rs5c372 as rtc0 Fix by initializing the name early.
