ARM: s3c64xx: squash samsung_usb_phy.h into setup-usb-phy.c

This is only used by arch/arm/mach-s3c64xx/setup-usb-phy.c

$ git grep samsung_usb_phy_type
include/linux/usb/samsung_usb_phy.h:enum samsung_usb_phy_type {
$ git grep USB_PHY_TYPE_DEVICE
arch/arm/mach-s3c64xx/setup-usb-phy.c:  if (type == USB_PHY_TYPE_DEVICE)
arch/arm/mach-s3c64xx/setup-usb-phy.c:  if (type == USB_PHY_TYPE_DEVICE)
include/linux/usb/samsung_usb_phy.h:    USB_PHY_TYPE_DEVICE,
$ git grep USB_PHY_TYPE_HOST
include/linux/usb/samsung_usb_phy.h:    USB_PHY_TYPE_HOST,

Actually, 'enum samsung_usb_phy_type' is unused; the 'type' parameter
has 'int' type. Anyway, there is no need to declare this enum in the
globally visible header. Squash the header.
