usb: phy: am335x: include linux/err.h

Stephen Rothwell reported that this driver does not compile on PowerPC
due to this missing include. One could argue why this driver is enabled
on PowerPC in the first place but it sure isn't wrong to include headers
for used function instead of to rely that they sneak in.
