interconnect: mediatek: Don't hijack parent device

Browse source

[ Upstream commit 510f821444 ]

If the intention is that users of the interconnect declare their
relationship to the child icc_emi node of the dvfsrc controller, then
this code never worked. That's because it uses the parent dvfsrc device
as the device it passes to the interconnect core framework, which means
all the OF parsing is broken.

Use the actual device instead, and pass the dvfsrc parent into the
dvfsrc calls.
