The MCAUSE register has the "Interrupt" flag defined defined at XLEN-1
position (31 for 32-bit, 63 for 64-bit). This is not an SoC specific
option, and there's no need to expose it publicly.

Because it was exclusively used by the "common" RISC-V privileged code
to build CPU idle routines that are now handled by arch level code.
Also, all platforms defaulted to "y", making it pointless in practice.

Introduce a new arch level Kconfig option to signal the implementation
of the RISCV Privileged ISA spec. This replaces
SOC_FAMILY_RISCV_PRIVILEGED, because this is not a SoC specific
property, nor a SoC family.
Note that the SoC family naming scheme will be fixed in upcoming
commits.

In an earlier commit, the riscv-privileged level implementation of
`arch_cpu_idle()` is not included unless `CONFIG_RISCV_HAS_CPU_IDLE` is
enabled.
This commit ensures the option is enabled on all the existing CPUs, thereby
maintaining the existing behavior.
Signed-off-by: Chen Xingyu <hi@xingrz.me>
The current configuration comes with a common implementation of
`arch_cpu_idle()` for the whole riscv-privileged family, utilizing the
`WFI` instruction to place the CPU into a light sleep state, with the
assumption that it will be awakened later by interrupts such as SYSTICK.
However, this approach is not always effective, particularly in scenarios
where the SYSTICK is not a valid wake source.
This commit uses `CONFIG_RISCV_HAS_CPU_IDLE` as the build condition of the
family-level `idle.c`, allowing CPUs that do not enable this option to
fallback to a generic arch-level implementation in
`arch/riscv/core/cpu_idle.c`.

Most of the public APIs in `riscv_plic.h`
(except `riscv_plic_get_irq` & `riscv_plic_get_dev`) expect the
`irq` argument to be in Zephyr-encoded format, instead of the
previously `irq_from_level_2`-stripped version. The first level
IRQ is needed by `intc_plic` to differentiate between the
parent interrupt controllers, so that correct ISR offset can be
obtained using the LUT in `sw_isr_common`.
