The tegra_cpuidle_pcie_irqs_in_use() function is stubbed out for non-ARM
builds, but now we can compile-test the Tegra pci driver on non-Tegra
ARM platforms as well, which results in a new link error:
drivers/pci/host/pci-tegra.o: In function `tegra_pcie_map_irq':
pci-tegra.c:(.text+0x288): undefined reference to `tegra_cpuidle_pcie_irqs_in_use'
drivers/pci/host/pci-tegra.o: In function `tegra_msi_map':
pci-tegra.c:(.text+0xba0): undefined reference to `tegra_cpuidle_pcie_irqs_in_use'
This adapts the #ifdef statement to match the exact condition under which
the function can be called.

The PCIe host controller found on Tegra20 has a hardware bug that causes
PCIe interrupts to get lost when LP2 is enabled. Stub out the workaround
on 64-bit ARM because none of the more recent Tegra SoC generations seem
to have this bug anymore.

In order to not clutter the include/linux directory with SoC specific
headers, move the Tegra-specific headers out into a separate directory.
