messages when registration fails (i.e. never).

944ed452eb rtc: remove unnecessary error message after platform_get_irq 
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.
