This series enables PCIe on the Qualcomm Nord SoC and brings up the WLAN
modules on the two reference boards.

Nord has four PCIe controllers fed by a single quadfurcated Gen5 QMP
multi-PHY.  The link topology (x16, x8+x8, x8+x4+x4 or x8+x4+x2+x2) is
selected by firmware through a TCSR register that the PHY driver reads at
probe time, so the DT only describes the PHY ports and hands the driver
the TCSR handle.  Patch 1 adds the PHY, the four controllers and the PCIe
SMMU; patches 2 and 3 enable them on the IQ10 Robotics Reference Design
and the Ride Embedded board respectively, along with the per-port PERST#
and WAKE# lines.

Patches 4 and 5 add the WCN7850 WLAN module sitting on PCIe2 on both
boards.  The two boards power the module differently: the Ride Embedded
connectivity adapter card derives the core rails from the module DBUs
gated by PWR_CORE and PWR_CTRL1, whereas the RRD generates them with
discrete on-board bucks behind a single core power enable.  Both are
described as they are wired.

This depends on the Nord Gen5x16 multi-PHY driver support [1], without
which the PHY does not probe.
