state of GEN_RTC vs rtc subsystem

[Kumar Gala]

Is the functionality provided by drivers/char/gen_rtc.c completely  
handled by the rtc subsystem in drivers/rtc?

I ask for two reasons:
1. should we make it mutually exclusive in Kconfig
2. I've enabled both and get (we'll my defconfig did):

proc_dir_entry 'rtc' already registered
