The datasheet for the rv3028 says the weekday has exact 3 bits
and in chapter 3.4.0 for the "3h–Weekday" register it says:
"""
This register holds the current day of the week. Each value represents
one weekday that is assigned by the user. Values will range from 0 to 6
The weekday counter is simply a 3-bit counter which counts up to 6
and then resets to 0.
"""
So do not code weekday bitwise instead, use the raw values from
0-6.
Tested on "PHYTEC phyBOARD-Pollux i.MX8MP" board.

The added device_property_present() call causes a build
failure in some configurations because of the missing header:

No functional change has been made with this patch. The main intent here
is to reduce code repetition of getting sensitivity attribute.
In the current implementation, sensor_hub_input_get_attribute_info() is
called from multiple drivers to get attribute info for sensitivity
field. Moving this to common place will avoid code repetition.

With this driver, mainline Linux can keep its time and date in sync with
the vendor kernel.
Advanced functionality like alarm and automatic power-on is not yet
supported.

The driver will compile with warning without OF because armada38x_data and
armada8k_data will be defined but not used. It would be possible to move
then in the #ifdef CONFIG_OF section but then their members will be defined
but not used. Instead of moving most of the driver in the #ifdef, simply
depend on OF.

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.

The recent fix for handling the UIP bit unearthed another issue in the RTC
code. If the RTC is advertised but the readout is straight 0xFF because
it's not available, the old code just proceeded with crappy values, but the
new code hangs because it waits for the UIP bit to become low.
Add a sanity check in the RTC CMOS probe function which reads the RTC_VALID
register (Register D) which should have bit 0-6 cleared. If that's not the
case then fail to register the CMOS.
Add the same check to mc146818_get_time(), warn once when the condition
is true and invalidate the rtc_time data.
