LoongArch: Mask all interrupts during kexec/kdump
If the default state of the interrupt controllers in the first kernel
don't mask any interrupts, it may cause the second kernel to potentially
receive interrupts (which were previously allocated by the first kernel)
immediately after a CPU becomes online during its boot process. These
interrupts cannot be properly routed, leading to bad IRQ issues.
This patch calls machine_kexec_mask_interrupts() to mask all interrupts
during the kexec/kdump process.
