The only user of Kconfig symbol EXYNOS_DEV_DRM was removed in commit
0a9d5ac3 ("ARM: EXYNOS: removing exynos-drm device registration
from non-dt platforms"). It is safe to remove this symbol too.

While waking up CPU from off state using clock domain force wakeup, restore
the CPU power state to ON state before putting CPU clock domain under
hardware control. Otherwise CPU wakeup might fail. The change is recommended
for all OMAP4+ devices though the PRCM weakness was observed on OMAP5
devices first.

As a result of weakness, lock-up is observed inside the hardware state
machine of local CPU PRCM and results are UN-predictable as per designers.
In software testing, we have seen hard-locks most of the time where system
gets frozen. With power domain state restored, system behaves correctly.

So update the code accordingly.

s3c_rtc_setname() tests for CONFIG_SAMSUNG_DEV_RTC or
CONFIG_PLAT_S3C24XX. But of these two macros only CONFIG_PLAT_S3C24XX
actually exists. Now we can see that s3c_device_rtc is only defined if
either CONFIG_PLAT_S3C24XX or CONFIG_S3C_DEV_RTC are defined. So,
apparently, it was intended to use CONFIG_S3C_DEV_RTC here.
