[PATCH 5.15 466/667] macintosh: via-pmu and via-cuda need RTC_LIB

[Greg Kroah-Hartman]

From: Randy Dunlap <rdunlap@xxxxxxxxxxxxx>

[ Upstream commit 9a9c5ff5fff87eb1a43db0d899473554e408fd7b ]

Fix build when RTC_LIB is not set/enabled.
Eliminates these build errors:

m68k-linux-ld: drivers/macintosh/via-pmu.o: in function `pmu_set_rtc_time':
drivers/macintosh/via-pmu.c:1769: undefined reference to `rtc_tm_to_time64'
m68k-linux-ld: drivers/macintosh/via-cuda.o: in function `cuda_set_rtc_time':
drivers/macintosh/via-cuda.c:797: undefined reference to `rtc_tm_to_time64'

Fixes: 0792a2c8e0bb ("macintosh: Use common code to access RTC")
