8be20c690b hv: multiarch: change to common page level
move _page_table_level to common, and rename functions and

9d95a6adb6 hv: riscv: fix stack allocation in cpu_ctx_save/cpu_ctx_restore
The RISC-V calling convention defines a full descending stack, where 'sp'
points to the last used stack address. The current implementation of
cpu_ctx_save() subtracts only CPU_REGS_OFFSET_SCRATCH from 'sp', which
allocates 8 bytes too few and may overwrite the caller's stack contents.

Fix this by adjusting CPU_REGS_OFFSET_LAST to include the last slot,
ensuring the full context save/restore area is properly reserved.

Fixes: 6276763cd (hv: riscv: implement cpu_ctx_save and cpu_ctx_restore)

fc495b946a hv: riscv: irq: add interrupt initialization and handlers
This patch implements interrupt initialization and the basic
exception/interrupt handling flow on RISC-V.

init_interrupt() needs to be invoked during CPU initialization to
set up the trap vector and enable the interrupt.

RISC-V exception and interrupt handling includes:
- Saving and restoring CPU registers around traps
- Implementing handlers for:
  - Supervisor software interrupt
  - Supervisor timer interrupt
- Halting the CPU for all other interrupts and exceptions

------
TODOs:
1. add support for registering interrupt handlers via request_irq() and
   further adoption of the common IRQ framework.
2. add support for external interrupt.
