Subject: X86: Impossible select Enhanced Real Time Clock Support (legacy PC
 RTC driver)

Since some kernel version it is impossible to select the Enhanced Real
Time Clock Support (legacy PC RTC driver) because RTC_LIB is set by
default in arch/x86/Kconfig, but the rule for selecting CONFIG_RTC is
RTC_LIB=n. So the code of driver/char/rtc is still useless.

This breaks the API since there is no more misc device /dev/rtc
available without a udev rule or a link to /dev/rtc0.
