Daniel Leung 44462723f5 timer: hpet: make legacy interrupt routing optional
On some platforms, HPET is not wired to trigger IRQ 2.
This would make HPET non-functional if the legacy
interrupt routing bit is set in the global config
register. This adds a DTS flag so the driver won't
set the bit to enable legacy interrupt.

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`_.
