[PATCHv2 2/4] tegra: Test on CONFIG_CMD_USB being enabled for distro bootcmd

[Tom Rini]

Reuse the common logic to allow for BOOT_TARGET_DEVICES to list USB as a
possibility if we're building for a platform that will have USB but not
if we don't, so that we don't hit the link-time check for trying to have
USB boot on a non-USB system.

Changes in v2:
- New patch.  This problem shows up later in the series when we stop
  building USB framework without a host controller of some sort also
  enabled.
