Johan Hovold 80574c4059 USB: phy: fsl-usb: fix missing static keywords 
A recent change enabling compile testing of a Freescale dual-role
controller indirectly enabled a USB PHY driver to be built. That driver
in turn is missing a bunch of static keywords which results in warnings
like:

drivers/usb/phy/phy-fsl-usb.c:105:5: error: no previous prototype for 'write_ulpi' [-Werror=missing-prototypes]
  105 | int write_ulpi(u8 addr, u8 data)
        |     ^~~~~~~~~~

which consequently breaks -Werror builds.

Add the missing static keywords.
