chromeos: add get_recovery_mode_from_vbnv() to vbnv_flash

Browse source 
The first platform that used flash-backed VBNV data has a physical
recovery switch, get_recovery_mode_from_vbnv() was never implemented.

This patch adds get_recovery_mode_from_vbnv() similarly to how it's
implemented for other vbnv storage in other places.
