c50b21b705 bootcount: add a new driver with syscon as backend
The driver will use a syscon regmap as backend and supports both
16 and 32 size value. The value will be stored in the CPU's endianness.

add DM/DTS support for the memory based bootcounter

Let the old implementation in, so boards which have

482734aa66 bootcount: add a DM RTC backing store for bootcount
This implements a driver using a RTC-based backing store for the DM
bootcount implementation.  The node configuring this feature will be
compatible with 'u-boot,bootcount-rtc' and the underlying RTC device
shall be reference through the property 'rtc'. An offset into the RTC
device's register space can be provided through the 'offset' property.

Tested on a RK3399-Q7 on a Flamingo carrier board using the SRAM area
of the carrier board's RV3029 RTC.

ebb73de168 bootcount: add uclass for bootcount
The original bootcount methods do not provide an interface to DM and
rely on a static configuration for I2C devices (e.g. bus, chip-addr,
etc. are configured through defines statically).  On a modern system
that exposes multiple devices in a DTS-configurable way, this is less
than optimal and a interface to DM-based devices will be desirable.

This adds a simple driver that is DM-aware and configurable via DTS.
If ambiguous (i.e. multiple bootcount-devices are present) the
/chosen/u-boot,bootcount-device property can be used to select one
bootcount device.

Initially, this provides support for the following DM devices:
 * RTC devices

39bcbb7740 bootcount: Migrate CONFIG_SYS_BOOTCOUNT_ADDR
Migrate the users of CONFIG_SYS_BOOTCOUNT_ADDR to Kconfig.  We can
provide a default for BOOTCOUNT_AM33XX as that's a specific part of the
RTC in use.  We can also provide a default for ARCH_LS1043A and
ARCH_LS1021A as they had been previously calculated and their symbols
are in Kconfig.  In the case of other QE-enabled platforms, they are not
so we must update the relevant defconfig files.  The previous default
only applied in some cases, even on a specific SoC family.
