[coreboot-gerrit] Change in coreboot[master]: device: Enable ASPM for TBT PCIe root ports

[John Zhao (Code Review)]

Hello build bot (Jenkins), Duncan Laurie, Utkarsh H Patel, Sukumar Ghorai,

I'd like you to reexamine a change. Please visit

https://review.coreboot.org/c/coreboot/+/47686

to look at the new patch set (#2).

Change subject: device: Enable ASPM for TBT PCIe root ports
......................................................................

device: Enable ASPM for TBT PCIe root ports

The virtual/generic device under TBT PCIe root ports has path type as
DEVICE_PATH_GENERIC. While scanning the pcie bus, the generic device
blocks its root ports configuration. This change adds device path type
check and enables ASPM for TBT root ports.

BUG=b:173207454
TEST=Built image and booted to kernel on Voxel board. Verified both of
the TBT Root ports 00:07.0 and 00:07.1 ASPM are enabled.
