Partially revert "usb: Kconfig: using select for USB_COMMON dependency"

commit 4d1aa911 upstream.

This reverts commit cb9c1cfc for
USB_LED_TRIG.  This config symbol has bool type and enables extra code
in usb_common itself, not a separate driver.  Enabling it should not
force usb_common to be built-in!
