arm64: dts: qcom: glymur: Describe display related nodes
The MDSS (Mobile Display SubSystem) on Glymur comes with 4 DisplayPort
controllers. Describe them along with display controller and the eDP
PHY. Then, attach the combo PHYs link and vco_div clocks to the Display
clock controller and link up the PHYs and DP endpoints in the graph.

arm64: dts: qcom: glymur-crd: Enable eDP display support
Enable the MDSS (Mobile Display SubSystem) along with the 3rd
DisplayPort controller and its PHY in order to bring support
for the panel on Glymur CRD platform. Also describe the voltage
regulator needed by the eDP panel.

dt-bindings: phy: qcom-edp: Add missing clock for X Elite
On X Elite platform, the eDP PHY uses one more clock called ref.

The current X Elite devices supported upstream work fine without this
clock, because the boot firmware leaves this clock enabled. But we should
not rely on that. Also, even though this change breaks the ABI, it is
needed in order to make the driver disables this clock along with the
other ones, for a proper bring-down of the entire PHY.

So attach the this ref clock to the PHY.

dt-bindings: phy: Add DP PHY compatible for Glymur
The Glymur platform is the first one to use the eDP PHY version 8.
This makes it incompatible with any of the earlier platforms and therefore
requires a dedicated compatible. So document it.

The Glymur USB system contains 3 USB type C ports, 1 USB multiport
controller and a USB 2.0 only controller. This encompasses 5 SS USB QMP
PHYs (3 combo and 2 uni) and 6 M31 eUSB2 PHYs. All controllers are SNPS
DWC3 based, so describe them as flattened DWC3 QCOM nodes.

The Qualcomm Glymur Compute Reference Device comes with 3 Type-C ports,
one USB Type-A, and a fingerprint reader connected over USB. Each of these
3 Type-C ports are connected to one of the USB combo PHYs and one of the
M31 eUSB2 PHYs. The Type-A is connected to the USB Multi-port controller
via one of the M31 eUSB2 PHYs and one combo PHY. The fingerprint reader
is connected to the USB_2 controller. All M31 eUSB2 PHYs have associated
eUSB2 to USB 2.0 repeaters, which are either part of SMB2360 PMICs or
dedicated NXP PTN3222.

So enable all needed controllers, PHYs and repeaters, while describing
their supplies. Also describe the PMIC glink graph for Type-C connectors.
