unicore32: move rtc-puv3.c to drivers/rtc directory

Browse source 
The patch moves rtc driver for PKUnity-v3 SoC from arch/unicore32/kernel/
to drivers/rtc/, with renaming it to rtc-puv3.c.
Also, Kconfig, Makefile, and MAINTAINERS are modified correspondingly.

This enables support for the RTC in the PKUnity-v3 SoCs.
This drive can also be built as a module. If so, the module
will be called rtc-puv3.
