[PATCH] rtc: Delete an error message in three functions

[PATCH] rtc: Delete an error message in three functions

The function “platform_get_irq” can log an error already.
Thus omit redundant messages for the exception handling in the
calling functions.

This issue was detected by using the Coccinelle software.
