char/genrtc: remove the rest of the driver

Browse Source 
No architecture uses the genrtc driver any more, so let's kill it off
for good. This now also includes asm-generic/rtc.h, which is otherwise
completely unused.

If you say Y here and create a character special file /dev/rtc with
major number 10 and minor number 135 using mknod ("man mknod"), you
will get access to the real time clock (or hardware clock) built
into your computer.
It reports status information via the file /proc/driver/rtc and its
behaviour is set by various ioctls on /dev/rtc. If you enable the
"extended RTC operation" below it will also provide an emulation
for RTC_UIE which is required by some programs and may improve
precision in some cases.
