we can as the conid + devid are prioritary than just the conid

so
	CLKDEV_CON_DEV_ID("hclk", "at91_ohci", &uhphs_clk),

I know that I have signed the patch *but* there is an issue here...

We cannot do this: it does not even compiles.
The ohci_clk clock is not existing on this device. Moreover, the "hclk"
con_id is already existing for the *gadget* device...

We have to correct this before I can send it upstream.
