cr50: return the time since user_pres was asserted
Add a vendor command that returns the time since user_pres_l was
asserted. This is only used for testing.
Tracking user_pres_l needs to be enabled with a vendor command since
DIOM4 may not be pulled up and may be pulled down on old boards.
Enabling the vendor command survives deep sleep reset. It gets cleared
after cr50 reset.
Cr50 clears the user_pres_l status if tracking is disabled.

# Verify it survives deep sleep

# Check gsctool output after triggering DIOM4 pulse
