usb: phy: Improve Kconfig help for CONFIG_USB_PHY 



The previous text confused users by not describing the very common
(e.g. x86 PC) sitations where no PHY driver is necessary.

	bool "USB Physical Layer drivers"

	help

	  USB controllers (those which are host, device or DRD) need a

	  device to handle the physical layer signalling, commonly called

	  a PHY.

	  Most USB controllers have the physical layer signalling part

	  (commonly called a PHY) built in.  However, dual-role devices

	  (a.k.a. USB on-the-go) which support being USB master or slave

	  with the same connector often use an external PHY.



	  The following drivers add support for such PHY devices.

	  The drivers in this submenu add support for such PHY devices.

	  They are not needed for standard master-only (or the vast

	  majority of slave-only) USB interfaces.



	  If you're not sure if this applies to you, it probably doesn't;

	  say N here.
