Jimmy Zheng a7096fac7d drivers: interrupt_controller: nuclei_eclic: always use clic common entry
When CONFIG_RISCV_VECTORED_MODE is disabled, CLIC claims interrupts using
CSR 'mnxti' and handles all pending interrupts before exiting the ISR.

When CONFIG_RISCV_VECTORED_MODE is enabled, all interrupts use vector mode
and are claimed automatically. The RISC-V common ISR is used for interrupts
hooked into SW ISR table, but it only handle one pending interrupt per ISR.

This commit enhances CLIC to set vector mode for direct ISRs only and use
the CLIC common entry for regular ISRs to handles multiple pending
interrupts in an ISR.

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-A,
Cortex-R, Cortex-M), Intel x86, ARC, Nios II, Tensilica Xtensa, and RISC-V,
SPARC, MIPS, and a large number of `supported boards`_.
