The device table is required to load modules based on
modaliases. After adding MODULE_DEVICE_TABLE, below entries
for example will be added to module.alias:
alias:          of:N*T*Csigma,smp8758-nandC*
alias:          of:N*T*Csigma,smp8758-nand

Fixes: 6956e238 ("mtd: nand: add tango NAND flash controller support")
