Subject: [PATCH v5 1/7] dt-bindings: phy: Add qcom,snps-eusb2-repeater schema file

The SM8550 SoC uses Synopsis eUSB2 repeater found in PM8550b.
Add a dt-binding schema for the new driver.

The v4 is here:
https://lore.kernel.org/all/20230207135551.1418637-2-abel.vesa@linaro.org/

Changes since v4:
 * added Krzysztof R-b tag
 * added description about what the eUSB repeater does

Changes since v3:
 * made this patch the first one in the series to fix the binding check
   for the 2nd patch.
 * dropped the compatible for pmic in the example. This is due to the
   dependency between this patch and the next one.
