Subject: [PATCH 0/4] MIPS: Loongson64: Sweeping build warnings

Hi all,

This series sweeped various build warnings for loongson3_defconfig.
This is based on next-20240507.

There are still some warnings remain in pm.c, those errors are
covered by [1].

Thanks

Subject: [PATCH 2/4] MIPS: Loongson64: Include bootinfo.h in dma.c

dma.c defined function plat_swiotlb_setup, which is declared in
bootinfo.h.

Fixes warning:
