google/fizz: fix LAN driver chip_info attachment

As a result of commit:
[711fb81] soc/intel/skylake: Swap PCI devfn resides in same PCI device

fizz's chip_info for the LAN driver is being overwritten/nulled, as the
LAN device is on function 2 (PCIe port 3), but the driver info was set
for the post-swapped PCIe port (1).
Move the driver chip_info to function 2/port 3, so that it follows the
PCI device function when swapped after FSP-s, and is correctly passed
to the LAN driver.

Test: boot google/fizz (teemo variant), check cbmem console and
verify ethernet MAC address and LED config correctly set.
