Introduce the UCSI PMIC Glink aux driver that communicates

The UCSI messaging is necessary on newer Qualcomm SoCs to
provide USB role switch and altmode notifications.

No way to test build this code without this option?
Nop, the QCOM_PMIC_GLINK is a build dependency, this can't be removed
Then perhaps the QCOM_PMIC_GLINK code needs to be fixed up to allow for
it to be built on all platforms properly? Otherwise you are
guaranteeing you will not get much, if any, build coverage and api
changes will cause this code to stagnate over time :(
The QCOM_PMIC_GLINK deps are:
depends on RPMSG
depends on TYPEC
depends on DRM
depends on NET
depends on OF
select AUXILIARY_BUS
select QCOM_PDR_HELPERS
What would be the changes needed here ?
