usb: phy: move some error messages to debug

Browse Source 
the PHY layer is supposed to be optional,
considering some PHY have no control bus
for SW to poke around.

After commit 1ae5799 (usb: hcd: Initialize
USB phy if needed) any HCD which didn't provide
a PHY driver would emit annoying error messages.

In this patch we're decreasing those messages
to debugging only and we also add a PHY prefix
or use dev_dbg so we know where they're coming from.
