dmaengine: pl08x: handle the rest of enums in pl08x_width
pl08x_width function does not handle rest of enums for DMA_SLAVE_BUSWIDTH_xxxx
which causes gcc to emit below warining
drivers/dma/amba-pl08x.c: In function 'pl08x_width':
drivers/dma/amba-pl08x.c:1119: warning: enumeration value
'DMA_SLAVE_BUSWIDTH_UNDEFINED' not handled in switch
drivers/dma/amba-pl08x.c:1119: warning: enumeration value
'DMA_SLAVE_BUSWIDTH_8_BYTES' not handled in switch
this patch adds a default case which returns error
