The patch "rtc: verify a critical argument to rtc_update_irq() before
using it" introduces validation for rtc_device in the RTC core, so there
are no need to check this argument for rtc_update_irq() from the
drivers.
This patch removes such check for the existing rtc_update_irq() users.

NO_IRQ may be defined as '(unsigned int) -1' in some architectures (arm,
sh ...), and either may not be defined in some architectures (arm64) which
can enable RTC_DRV_S3C.
Also since platform_get_irq returns err-code in case of any error, we do
not need to intialize s3c_rtc_alarmno and s3c_rtc_tickno.

Using platform_get_irq_byname() to retrieve the IRQ number returns the
VIRQ number rather than the local IRQ number for the device. Passing that
value then into regmap_irq_get_virq() causes a failure because the
function is expecting the local IRQ number (e.g. 0, 1, 2, 3, etc).
This patch removes use of regmap_irq_get_virq() to prevent this failure
from happening

Add support for describing the PM8921/PM8058 RTC in device tree.
Additionally:

as there are no current in tree users who do so.
- make allow_set_time a device-specific flag, instead of mucking
with the rtc_ops

CONFIG_PM will be set also if only CONFIG_PM_RUNTIME is set which causes
the compiler to emit following warning:
drivers/rtc/rtc-cmos.c:845:12: warning: =E2=80=98cmos_resume=E2=80=99 defined but not used [-Wunused-function]
Fix this by using CONFIG_PM_SLEEP instead of CONFIG_PM and removing it
from the driver pm ops as this has been taken care by
SIMPLE_DEV_PM_OPS() already.

Datasheet says: "When the VSRTC voltage drops to the range of 0.9 - 0.8V,
the RTCPORB reset signal is generated and the contents of the RTC will
be reset. <skip>. To inform the processor that the contents of the RTC
are no longer valid due to the reset, a timer reset interrupt function
is implemented with the RTCRSTI bit." This patch makes the RTC valid by
default until RTCRST interrupt occurs.
