Zide Chen f32eeba925 dts: x86: configure different IO APIC delivery modes for various devices
For HPET devices, configure it with fixed delivery mode because HPET
timer interrupt is needed to fuel the scheduler for all CPUS.

For all other type of devices, like UART, I2C, GPIO, Ethernet, etc.
configure them as lowest priority delivery mode, in which IO APIC
delivers the interrupt to the processor core that is executing at the
lowest priority among all the processors listed in the specified
destination. In this case, the device drivers can avoid the trouble of
handling repeated interrupts delivered to all CPUS.

The Zephyr Project is a scalable real-time operating system (RTOS) supporting
multiple hardware architectures, optimized for resource constrained devices,
and built with security in mind.

The Zephyr OS is based on a small-footprint kernel designed for use on
resource-constrained systems: from simple embedded environmental sensors and
LED wearables to sophisticated smart watches and IoT wireless gateways.

The Zephyr kernel supports multiple architectures, including ARM Cortex-M,
Intel x86, ARC, Nios II, Tensilica Xtensa, and RISC-V, and a large number of
`supported boards`_.
