Add I2C_TARGET_ALLOW_POWER_SAVING config. Enable this config makes I2C
target device can enter Doze/Deep doze states while the bus is idle.
Ongoing transfers will block low-power entry until they are completed,
ensuring correct communication while still reducing overall power
consumption.

PM on the nrf54h20 has minimal utility if power domains and devices

Add image properties data structure to Series 2 binaries.
This data structure is used by the SE or bootloader to enforce

for the image version field. Set image type based on Kconfig
options.

Added support for the IronSide bootmode service which allows requesting
a reboot into secondary firmware boot mode. In this mode, the secondary
configuration defined in UICR is applied instead of the primary one.
The service provides the ironside_bootmode_secondary_reboot() function
that can pass message data to the boot report of the CPU booted in the
secondary boot mode.

The CMC interface controls the entry and exit of the
CPU's low-power mode and the identification of the wake-up source.
To ensure the normal operation of the system's low-power timing sequence,
when transfer IDLE_RUN to IDLE_SLEEP, it is necessary to ensure
that the system is not awakened by the wake-up source during this stage.
Therefore, an IRQ MASK needs to be set on the CMC
Before the CPU enters the low power mode, a wake up mask needs to be set
according to the situation where the interrupt controller is enabled
at that time.
After the cpu exits the low power mode, resume needs to be performed

Add initial support for the Versal Net SoC APU, which is based on
the Arm Cortex-A78 processor. It includes basic wiring for memory
regions, UART, interrupt controller, and timer.
The versalnet_apu.dtsi file defines peripherals shared across the SoC,
while versalnet_a78.dtsi captures peripherals private to the Cortex-A78
processor. These device trees lay the groundwork for further APU-based
development on the Versal Net platform.
