Re: [PATCH v7 14/22] riscv: Clear pending interrupts before enabling IPIs

On some platforms (k210), the previous stage bootloader may have not cleared pending IPIs before transferring control to U-Boot. This can cause race conditions, as multiple harts all attempt to initialize the IPI controller at once. This patch clears IPIs before enabling them, ensuring that only one hart modifies shared memory at once.
