Mario Limonciello d2d8ceb748 rtc: mc146818-lib: Adjust failure return code for mc146818_get_time()
commit af838635a3eb9b1bc0d98599c101ebca98f31311 upstream.

mc146818_get_time() calls mc146818_avoid_UIP() to avoid fetching the
time while RTC update is in progress (UIP). When this fails, the return
code is -EIO, but actually there was no IO failure.

The reason for the return from mc146818_avoid_UIP() is that the UIP
wasn't cleared in the time period. Adjust the return code to -ETIMEDOUT
to match the behavior.
