PowerPC is the last architecture using the GEN_RTC driver on some machines, but we can migrate them all to using the RTC_DRV_GENERIC driver instead now. This moves over the CONFIG_GEN_RTC option from drivers/char into arch/powerpc/platforms/Kconfig and makes it just select the replacement driver instead, for the only reason of not breaking existing defconfig and .config files that users may have.
