rtc: generic: allow building on all architectures
There are four architectures using this driver, but since we can
build it with COMPILE_TEST, we should try dealing with the absence
of the asm/rtc.h header file, to avoid getting a build error:
drivers/rtc/rtc-generic.c:12:21: fatal error: asm/rtc.h: No such file or directory
This creates an alternative use of the driver, allowing architectures
to pass a set of rtc_class_ops in platform data. We can convert the
four architectures to use this and then remove the original
code.
