dmaengine: shdma: increase size of 'dev_id'

We seem to have hit warnings of 'output may be truncated' which is fixed
by increasing the size of 'dev_id'

drivers/dma/sh/shdmac.c: In function ‘sh_dmae_probe’:
drivers/dma/sh/shdmac.c:541:34: error: ‘%d’ directive output may be truncated writing between 1 and 10 bytes into a region of size 9 [-Werror=format-truncation=]
