Add support for the PHYs and controllers used for USB on SM8750 SoCs.

Version-6 of this series has all the binding/driver/dt patches acked.
But only the phy changes have been merged. Version 7 was a rebase to get
acked patches merged. But comments came in to use flattened bindings.
The v8 for usb bindings patch has been split and sent out separately [1]
and it is ACKed. On v10, the pmic glink changes and usb role switch
support are added while addressing some comments obtained.

Defconfig patch has been resent by Jingyi on [2].

---
Changes in v11:
- Fixed commit header in QRD patch.
- Reordered nodes to be in alphabetical order.
- Link to v10: https://lore.kernel.org/all/20251031123354.542074-1-krishna.kurapati@oss.qualcomm.com/

Changes in v10:
- Squashed pmic-glink changes from [3] in this series.
- Added remote endpoints between connector and usb nodes.
- Added Jishnu's CDB & SOB tag to credit for pmic glink changes.
- Renamed "usb_1"  to "usb" as per comments from Bjorn.
- Added QMP Phy pipe clock in GCC properties as per comments from Dmitry.
- Link to v9: https://lore.kernel.org/all/20251024151521.2365845-1-krishna.kurapati@oss.qualcomm.com/

Changes in v9:
- Updated commit tags (Removed Suggested-by of Konrad andadded his SoB)
- Confirmed with Konrad offline before adding his Signed-off-by
- Updated commit text in patch 1/3 as per suggestion from Bjorn.
- Link to v8: https://lore.kernel.org/all/20251022084052.218043-1-krishna.kurapati@oss.qualcomm.com/

Changes in v8:
- Using Flattened DT representation.
- Removed obtained RB tags since the code has changed significantly.
- Modified Author mail address from quicinc to oss.qualcomm.com
- Link to v7: https://lore.kernel.org/all/20251015105231.2819727-1-krishna.kurapati@oss.qualcomm.com/

Changes in v7:
- Rebased on top of linux next
- Split usb patch and sent out separately.
- Link to v6: https://lore.kernel.org/all/20250527-sm8750_usb_master-v6-0-d58de3b41d34@oss.qualcomm.com/

Changes in v6:
- Change readl_relaxed/writel_relaxed calls to just readl/writel in the readback function
- Updated languange in the defconfig commit to specify SM8750 as a Qualcomm SoC
- Link to v5: https://lore.kernel.org/r/20250421-sm8750_usb_master-v5-0-25c79ed01d02@oss.qualcomm.com

Changes in v5:
- Removed refclk_src from the QMP PHY driver as that is no longer used.
- The decision to move the TCSR clkref property from controller --> phy
node was made in v4, and the refclk_src was a lingering change that was
meant to be removed.  CXO is the parent clock for TCSR clkref, so CXO
clk will be voted for as well.
- Relocate the SM8750 compatible within the qcom,dwc3 bindings.  This is
to take into account the change in clock list.
- Link to v4: https://lore.kernel.org/r/20250409-sm8750_usb_master-v4-0-6ec621c98be6@oss.qualcomm.com

Changes in v4:
- Made some fixups to the M31 eUSB2 driver
- Moved TCSR refclk_en to the QMP PHY DT node
- Link to v3: https://lore.kernel.org/r/20250324-sm8750_usb_master-v3-0-13e096dc88fd@quicinc.com

Changes in v3:
- Split platform DTs into separate commits.
- Fixed up M31 eUSB2 PHY driver with feedback received.
- Reordered DT properties based on feedback.
- Rewrote commit message for enabling EUSB driver.
- Link to v2: https://lore.kernel.org/r/20250304-sm8750_usb_master-v2-0-a698a2e68e06@quicinc.com

Changes in v2:
- Added new QMP PHY register definitions for v8 based QMP phys.
- Made changes to clean up some code in the M31 eUSB2 PHY driver based
on feedback received.
- Added bulk regulator operations in M31 eUSB2 PHY, to ensure that
both the vdd and vdda12 regulators are properly voted for.
- Removed external references to other dt bindings in M31 example for
the DT bindings change.
- Split DT patches between SoC and plaform changes, as well as the
PHY subsystem Kconfig changes when introducing the M31 eUSB2 PHY.
- Added orientation switch and port definitions in the DT changes.EDITME: describe what is new in this series revision.
