for i.MX51 but broke it for (at least) i.MX27 which doesn't have
a usb_phy1 clock but has a pdev->id 0.

ouch. Sorry for this. I didn't thought that imx51 was an exception
rather than the rule. Also, I think that imx53 may deserve same
treatment but I've neither a  imx53 nor its datasheet at hand to check
that.

thanks,
Arnaud
