The compatibles have been marked obsolete for more that 2 years, drop them
now. Note that this doesn't currently prevent the driver from probing
because the i2c core will still match using the i2c_device_id table.

The RV3029 can report three different conditions: power on, voltage dropped
and data is lost and voltage is low and temperature compensation has
stopped. The first two conditions amount to the same status, the RTC data
is invalid.
VLOW1 has to be cleared manually to resume temperature compensation, this
is achieved using RTC_VL_CLEAR.

There is no point in having 2 indirections before calling regmap_read,
especially since rv3029_get_sr also changes the return value without any
good reason. Call regmap_read directly.

There is no lock preventing concurrent access to the status register from
bth the rtc subsystem and the hwmon subsystem. Use regmap_update_bits to
ensure updating RV3029_STATUS is properly locked.

Instead of trying to validate the accessed registers in custom functions,
let regmap handle that. This allows to defines all the holes in the
register range and gives access to the regmap debugfs register dump.

RV8803_FLAG_V1F means the voltage is too low to keep the temperature
compensation running and the accuracy of the RTC is affected.
RV8803_FLAG_V2F means the voltage dropped so low that data is now invalid.

voltage_low is only updated when reading the time, this means that using
RTC_VL_READ will miss the VL flag if the time has not been read before
using the ioctl. Always read the status from the hardware.

Currently, the meaning of the value returned by RTC_VL_READ is undocumented
and left to the driver implementation. In order to get more meaningful
values, define a set of values to use as to make clear to userspace what is
the status of the various voltages feeding the RTC.

The current use of mode flags to us SPI_MODE_3 and
SPI_CS_HIGH is fragile: it overwrites anything already
assigned by the SPI core. Change it thusly:
- Just |= the SPI_MODE_3 so we keep other flags
- Assign ^= SPI_CS_HIGH since we might be active high
already, and that is usually the case with GPIOs used
for chip select, even if they are in practice active low.
Add a comment clarifying why ^= SPI_CS_HIGH is the right
choice here.
