arm: a37xx: pci: Fix configuring PCIe resources

The `ranges` DT property of the PCIe node is currently ignored by
Aardvark driver - all entries are used as transparent PCIe MEM, despite
some of them being defined for IO in DT.

This is because the driver does not setup PCIe outbound windows and thus
a default configuration is used.

This can cause an external abort on CPU when a device driver tries to
access non-MEM space.

Setup the PCIe windows according to the `ranges` property for all
non-MEM resources (currently only IO) and also non-transparent MEM
resources.

Because Linux expects that bootloader does not setup Aardvark PCIe
windows, disable them before booting Linux.
