[PATCH v3] powerpc/configs: enable RTC class support

[Vaibhav Jain]

A working rtc kernel driver is needed so that hwclock can synchronize
system clock to rtc during shutdown/boot. We already have a rtc platform
driver for power arch located at drivers/rtc/rtc-opal.c However it
depends on CONFIG_RTC_CLASS which is disabled by default. So this driver
is not compiled with pseries defconfig as rtc class support is missing
from the kernel.

We fix this by enabling rtc class support in pseries defconfig so that
this driver gets enabled and is compiled into the pseries kernel.
