[3/3] usb: typec: fusb302: Populate tcpc fwnode for TCPM property handling

Commit Message

This update populates the tcpc handle's fwnode pointer with the
child usb-connector node, if it exists, so that TCPM can perform
generic property handling to define the ports capabilities.

I've applied this patch to my tree:
https://github.com/krohei/linux/commit/bc5614cfe29eb48494eaf88845f57a49ae5c1967

I will resend it to Greg together with all the other Type-C patches
that are ready next week after v4.19-rc4 unless Greg has picked it
himself before that.


Thanks,

Patch
