dmi: Fix build breakage

Commit d7b1956fed33d30c4815e848fd7a143722916868 ("DMI: Introduce
dmi_first_match to make the interface more flexible") introduced compile
errors like the following when !CONFIG_DMI

drivers/ata/sata_sil.c: In function 'sil_broken_system_poweroff':
drivers/ata/sata_sil.c:713: error: implicit declaration of function 'dmi_first_match'
drivers/ata/sata_sil.c:713: warning: initialization makes pointer from integer without a cast

We just need a dummy version of dmi_first_match() to fix this all up.
