soc: qcom: add UCSI function to PMIC GLINK
The PMIC GLINK interface offers an UCSI endpoint for newer
SoCs, the UCSI exchange is necessary to configure the USB-C
port USB role and altmode on the SM8450 HDK and SM8550 MTP
boards.
This patchset focuses on USB and disables altmode support
on those 2 SoCs until DP altmode over the combo phy is
supported.
Depends on PMIC Glink patchset at [1].
