[Daniel Gomez]

MODULE_DEVICE_TABLE(of, <of_match_table> should be called to complete DT
OF mathing mechanism and register it.

Before this patch:
modinfo drivers/mfd/madera-spi.ko  | grep alias
alias:          spi:wm1840
alias:          spi:cs47l91
alias:          spi:cs47l90
alias:          spi:cs47l85
alias:          spi:cs47l35

After this patch:
modinfo drivers/mfd/madera-spi.ko  | grep alias
alias:          spi:wm1840
alias:          spi:cs47l91
alias:          spi:cs47l90
alias:          spi:cs47l85
