rtc/alpha: remove legacy rtc driver 



The old drivers/char/rtc.c driver was originally the implementation
for x86 PCs but got subsequently replaced by the rtc class driver
on all architectures except alpha.

Move alpha over to the portable driver and remove the old one
for good.

The CONFIG_JS_RTC option was only ever used on SPARC32 but
has not been available for many years, this was used to build
the same rtc driver with a different module name.

config RTC

	---help---

	  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.



	  Every PC has such a clock built in. It can be used to generate

	  signals from as low as 1Hz up to 8192Hz, and can also be used

	  as a 24 hour alarm. It reports status information via the file

	  /proc/driver/rtc and its behaviour is set by various ioctls on

	  /dev/rtc.



	  If you run Linux on a multiprocessor machine and said Y to

	  "Symmetric Multi Processing" above, you should say Y here to read

	  and set the RTC in an SMP compatible fashion.



	  If you think you have a use for such a device (such as periodic data

	  sampling), then say Y here, and read <file:Documentation/admin-guide/rtc.rst>

	  for details.



	  To compile this driver as a module, choose M here: the

	  module will be called rtc.
