dmaengine: dw-edma: fix unnecessary stack usage
Putting large constant data on the stack causes unnecessary overhead
and stack usage:
drivers/dma/dw-edma/dw-edma-v0-debugfs.c:285:6: error: stack frame size of 1376 bytes in function 'dw_edma_v0_debugfs_on' [-Werror,-Wframe-larger-than=]
Mark the variable 'static const' in order for the compiler to move it
into the .rodata section where it does no such harm.
Fixes: 305aebeff879 ("dmaengine: Add Synopsys eDMA IP version 0 debugfs support")
