Haotian Zhang 5998ad91f8 rtc: gamecube: Check the return value of ioremap() 
[ Upstream commit d1220e47e4 ]

The function ioremap() in gamecube_rtc_read_offset_from_sram() can fail
and return NULL, which is dereferenced without checking, leading to a
NULL pointer dereference.

Add a check for the return value of ioremap() and return -ENOMEM on
failure.

Fixes: 86559400b3 ("rtc: gamecube: Add a RTC driver for the GameCube, Wii and Wii U")
