Subject: [PATCH 04/32] stmmac: pci: Select quark_pci_dmi_data from
 quark_default_data

Commit 7bc519b3ea04026877242328d2fe73cc8e6102bd upsteam.

No need to carry this reference in stmmac_pci_info - the Quark-specific
setup handler knows that it needs to use the Quark-specific DMI table.
This also allows to drop the stmmac_pci_info reference from the setup
handler parameter list.
