Add nodes for the two additional TC9563 PCIe switches present on the
QCOM RB3Gen2 Industrial Mezzanine platform.
One of the TC9563 is connected directly to the PCIe0 root-port while
the second TC9563 switch is connected in cascade fashion to another
already available TC9563 switch on PCIe1 via the former's downstream
port (DSP). The final PCIe hierarchy on the Industrial Mezz platform
would look something like below:

Changes in v5:
- Rename fixed-regulator node names as per current format (Krzysztof)
- Squash WCN6750 and WPSS disable changes for Industrial Mezzanine (Dmitry)
- Correct the pinctrl function for PCIe0 CLKREQ GPIO
- Link to v4: https://lore.kernel.org/r/20260305-industrial-mezzanine-pcie-v4-0-1f2c9d1344d7@oss.qualcomm.com
Changes in v4:
- Added the perst and related pincntrl gpios, due to default state of perst
we are not seeing any issue with v3.
- Corrected actual i2c address after cross verifing from the spec, as we
not updating anything through devicetree properties we are not seeing
any functional issue.
- Removed extra dummy regulator as per latest discussions.
- Link to v3: https://lore.kernel.org/r/20260212-industrial-mezzanine-pcie-v3-0-1e152937a76a@oss.qualcomm.com
Changes in v3:
- Fixed DT binding errors.
- Removed labels from unused TC9563 switch ports. (Konrad)
- Sort nodes in alphabetical order. (Dmitry)
- Fixed styling issues (Konrad)
- Link to v2: https://lore.kernel.org/r/20260203-industrial-mezzanine-pcie-v2-0-8579ed6bf931@oss.qualcomm.com
Changes in v2:
- Posted as v2 by error. Please consider as v1.
