For the existing APIs doing this the device used for the request is the
client device, not the providing device.  The APIs then have a mapping
table (clkdev for most of the clk APIs) which means that boards can then
assign providers to users without needing either of the drivers to know
what's going on, though of course they can be coded that way.
