Revert "Apexq: USB OTG"

This reverts commit 82071e3bed317ee8fdf93019e45e299a574718c3.

Add USB Host Notify driver

This is a requirement for proper host/otg function.

Copied from jf kernel. Enabled for Apexq only.

d2 probably wants this as well, but needs to consider
the implications of it on their own.

Added a bit more jf code to filter out the otg control
of charging and power supply via pm8921, which is not
relevant.

More jf code and now it actually works on apexq.
Probably require some massaging to make it work with d2.

--cleanup leftovers in the apexq board file.
