[PATCH v6 13/20] bootstd: Keep track of use of usb stop
When 'usb stop' is run, doing 'bootflow scan' does not run the USB hunter again so does not see any devices. Fix this by telling bootstd about the state of USB.

Changes in v6: - Ensure that bootstd functions are not called in SPL

U-Boot should set up the SMBIOS tables during startup, as it does on x86. Ensure that it does this correctly on non-x86 machines too, by creating an event spy for last-stage init.
Tidy up the installation-condition code while we are here.

Changes in v6: - Add a condition for mvebu_db-88f3720 last-stage init
Changes in v4: - Rewrite this to use events instead
Changes in v3: - Use log_debug() to show the message - Squash in the next patch
Changes in v2: - Add new patch
