PCI: Disable Hypertransport quirk on Tegra
The host bridge on Tegra is not visible on the PCI bus, and therefore
this quirk causes the following warning in the boot log:
[ 4.373017] pci 0000:00:01.0: nv_msi_ht_cap_quirk didn't locate host bridge
Since the quirk requires access to the host bridge's PCI configuration
space it cannot work on Tegra, so simply disable it in that case.
