PCI: Disable Hypertransport quirk on Tegra

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.

This changes define from ARCH_TEGRA to PLATFORM_TEGRA
