Some cleanups of the way we probe DMI platforms in the driver. Reduces
a bit of open-coding and makes the logic easier reusable for any
potential DMI platform != Quark.
Tested on IOT2000 and Galileo Gen2.
Changes in v4:
- Refactor patch 5 according to feedback
Jan
Jan Kiszka (6):
stmmac: pci: Make stmmac_pci_info structure constant
stmmac: pci: Use stmmac_pci_info for all devices
stmmac: pci: Make stmmac_pci_find_phy_addr truly generic
stmmac: pci: Select quark_pci_dmi_data from quark_default_data
stmmac: pci: Use dmi_system_id table for retrieving PHY addresses
stmmac: pci: Remove setup handler indirection via stmmac_pci_info

2.12.3
Move the special case for the early Galileo firmware into
quark_default_setup. This allows to use stmmac_pci_find_phy_addr for
non-quark cases.

By removing the PCI device reference from the structure and passing it
as parameters to the interested functions, we can make quark_pci_info
const.

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.
