PCI: iproc: Add arm64 support

Add arm64 support to the iProc PCIe driver.

Note that on arm32, bus->sysdata points to the arm32-specific
pci_sys_data struct, and pci_sys_data.private_data contains the
iproc_pcie pointer. For arm64, there's nothing corresponding to
pci_sys_data, so we keep the iproc_pcie pointer directly in
bus->sysdata.

In addition, arm64 does IRQ mapping in pcibios_add_device(), so it
doesn't need pci_fixup_irqs() as arm32 does.

In terms of peripherals the rk3368 is quite similar to the rk3288, which
makes it possible to have a lot basic components working in the first go.
More to follow once I tracked down all the tiny differences that still
exist in some parts.

With these dts files, the R88 board is able to boot from an attached
usb device and most likely from its emmc too, if the emmc uses a standard
partition table instead of Rockchip's own one - the emmc itself is
detected correctly.

This reverts commit dec4f799.

Jörg Otte reports a NULL pointder dereference due to this commit, as
'crtc_state' very much can be NULL:

        crtc_state = state->base.state ?
                intel_atomic_get_crtc_state(state->base.state, intel_crtc) : NULL;

So the change to test 'crtc_state->base.active' cannot possibly be
correct as-is.

There may be some other minimal fix (like just checking crtc_state for
NULL), but I'm just reverting it now for the rc2 release, and people
like Daniel Vetter who actually know this code will figure out what the
right solution is in the longer term.
