[PATCH v2] powerpc/cell: Code cleanup for spufs_mfc_flush

From: Kunwu Chan
Date: Thu Jan 25 2024 - 21:13:22 EST


This part was commented from commit a33a7d7309d7
("[PATCH] spufs: implement mfc access for PPE-side DMA")
in about 18 years before.

If there are no plans to enable this part code in the future,
we can remove this dead code.
