If DRAM calibration fails or mem test fails using the cached calibration
results stored in flash, rerun DRAM full calibration. If partial
calibration fails or the mem test following it fails, hang forever.
Partial calibration acts as a fallback approach in case of full
calibration failure. Therefore, if it fails, there would be no other
ways to initialize DRAM. Instead of falling into reboot loop and
draining out of battery, it is better to just hang so that the end user
may notice that and send to RMA.

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

With the default CPU voltage (0.8v), CPU frequency should be 1417Mhz at
most. We have to raise CPU frequency to 1989MHz after increasing CPU
voltage to 1.05v in romstage.
