rtc: s3c: stop setting bogus time
...
It doesn't make sense to set the RTC to a default value at probe time. Let
the core handle invalid date and time.
Also, this is basically dead code since commit 22652ba724https://lore.kernel.org/r/20210202112934.3612726-1-alexandre.belloni@bootlin.com

The Xilinx zynqmp RTC driver makes use of IOMEM functions like
devm_platform_ioremap_resource(), which are only available if
CONFIG_HAS_IOMEM is defined.
This causes the driver not to be enable under make ARCH=um allyesconfig,
even though it won't build.
By adding a dependency on HAS_IOMEM, the driver will not be enabled on
architectures which don't support it.

rtc: pcf2127: Disable Power-On Reset Override
...
To resume normal operation after a total power loss (no or empty
battery) the "Power-On Reset Override (PORO)" facility needs to be
disabled.
The register reset value sets the PORO enabled and the data sheet
recommends setting it to disabled for normal operation.
From what I've seen on the PCF2127 and PCF2129 there is no event
generated at the interrupt pin (INT), as long the PORO bit is set. This
behavior is not documented in the manual.
