Anatolij Gustschin 9473e8cfc7 usb: phy: fix build breakage 
Commit 94ae9843 (usb: phy: rename all phy drivers to phy-$name-usb.c)
renamed drivers/usb/phy/otg_fsm.h to drivers/usb/phy/phy-fsm-usb.h
but changed drivers/usb/phy/phy-fsm-usb.c to include not existing
"phy-otg-fsm.h" instead of new "phy-fsm-usb.h". This breaks building:
  ...
  drivers/usb/phy/phy-fsm-usb.c:32:25: fatal error: phy-otg-fsm.h: No such file or directory
  compilation terminated.
  make[3]: *** [drivers/usb/phy/phy-fsm-usb.o] Error 1

This commit also missed to modify drivers/usb/phy/phy-fsl-usb.h
to include new "phy-fsm-usb.h" instead of "otg_fsm.h" resulting
in another build breakage:
  ...
  In file included from drivers/usb/phy/phy-fsl-usb.c:46:0:
  drivers/usb/phy/phy-fsl-usb.h:18:21: fatal error: otg_fsm.h: No such file or directory
  compilation terminated.
  make[3]: *** [drivers/usb/phy/phy-fsl-usb.o] Error 1

Fix both issues.
