Some VRX518 modems fail to initialize properly with the error message
"dc_ep_clk_on failed". As a result, the DSL data path doesn't work.
This hack, which is based on code from the FRITZ!Box 7530 GPL archive,
fixes the issue. It changes the PCIe vendor/device ID to values matching
a Lantiq SoC. It also appears to emulate a Lantiq CPU ID register for
connected PCIe devices, by remapping the matching address area to a
specially crafted buffer using the address translation unit.
A dedicated compatible is created to activate this in
the device tree, so this shouldn't affect any devices other than
FRITZ!Box 7530/7520.
