The SM8550 SoC uses Synopsis eUSB2 PHY. Add a dt-binding schema
for the new driver.

The v5 version of this patch was here:
https://lore.kernel.org/all/20230207114024.944314-2-abel.vesa@linaro.org/

Changes since v5:
 * added Rob's R-b tag

Changes since v4:
 * none

Changes since v3:
 * removed blank line, like Rob suggested
 * dropped quotes and reset description, like Rob suggested
 * dropped the RPMH_CXO_PAD_CLK clock and the ref_src clock name
   to match the schema
 * fixed filenames of the includes in the example (sm8550-gcc and
   sm8550-tcsr)

Changes since v2:
 * none

Changes since v1:
 * dropped the "ref src" clock
 * dropped the usb-repeater property
