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

Set this option to indicate to vboot that this platform will skip its
display initialization on a normal (non-recovery, non-developer) boot.
Vboot calls this "oprom matters" because on x86 devices this
traditionally meant that the video option ROM will not be loaded, but
it works functionally the same for other platforms that can skip their
native display initialization code instead.
Unless display is specifically requested, the video option ROM is not
loaded, and any other native display initialization code is not run.
