rtc-proc: permit the /proc/driver/rtc device to use other devices
To get time information via /proc/driver/rtc, only the first device (rtc0)
is used. If the rtcN (eg. rtc1 or rtc2) is used for the system clock,
there is no way to get information of rtcN via /proc/driver/rtc. With
this patch, the time data can be retrieved from the system clock RTC.
If the RTC_HCTOSYS_DEVICE is not defined, then rtc0 is used by default.
