dmaengine: sh: make array ds_lut static
Don't populate the read-only array ds_lut on the stack but instead it
static. Also makes the object code smaller by 163 bytes:
Before:
text data bss dec hex filename
23508 4796 0 28304 6e90 ./drivers/dma/sh/rz-dmac.o
After:
text data bss dec hex filename
23281 4860 0 28141 6ded ./drivers/dma/sh/rz-dmac.o
(gcc version 11.2.0)
