[PATCH 1/5] rtc: gamecube: Propagate address translation error

[Thorsten Blum <blum@kernel.org>]

If of_address_to_resource() fails, propagate its error code instead of
returning -1 from gamecube_rtc_read_offset_from_sram().

Fixes: 86559400b3ef ("rtc: gamecube: Add a RTC driver for the GameCube, Wii and Wii U")
