rGc47cefba8312: Only build USB-related modules if MK_USB != no

So there's two competing mechanism now for usb: the kernel config file (which better not be setting this) and the user WITH/WITHOUT mechanism. This is a bit weird and novel for the kernel and may or may not be easy to support in configng.

  • Re-add drivers that got accidentally removed in the earlier diff.
  • Put ufshci back: I mistakingly though the driver was related to USB, but it's not.
