vboot: refactor OPROM code

Browse Source 
The name OPROM is somewhat inaccurate, since other steps to bring
up display and graphics are needed depending on mainboard/SoC.
This patch cleans up OPROM code nomenclature, and works towards
the goal of deprecating vboot1:

* Rename CONFIG_VBOOT_OPROM_MATTERS to
  CONFIG_VBOOT_MUST_REQUEST_DISPLAY and clarify Kconfig
  description
* Remove function vboot_handoff_skip_display_init
* Remove use of the VbInit oflag VB_INIT_OUT_ENABLE_DISPLAY
* Add |flags| field to vboot_working_data struct
* Create VBOOT_FLAG_DISPLAY_REQUESTED and set in vboot_handoff

TEST=make clean && make test-abuild
