security/vboot: Deprecate VBOOT_VBNV_EC
Boards using VBOOT_VBNV_EC (nyan, daisy, veyron, peach_pit) are all
ChromeOS devices and they've reached the end of life since Feb 2022.
Therefore, remove VBOOT_VBNV_EC for them, each with different
replacement.
- nyan (nyan, nyan_big, nyan_blaze): Add RW_NVRAM to their FMAP (by
reducing the size of RW_VPD), and replace VBOOT_VBNV_EC with
VBOOT_VBNV_FLASH.
- veyron: Add RW_NVRAM to their FMAP (by reducing the size of
SHARED_DATA), and replace VBOOT_VBNV_EC with VBOOT_VBNV_FLASH. Also
enlarge the OVERLAP_VERSTAGE_ROMSTAGE section for rk3288 (by reducing
the size of PRERAM_CBMEM_CONSOLE), so that verstage won't exceed its
allotted size.
- daisy: Because BOOT_DEVICE_SPI_FLASH is not set, which is required for
VBOOT_VBNV_FLASH, disable MAINBOARD_HAS_CHROMEOS and VBOOT configs.
- peach_pit: As VBOOT is not set, simply remove the unused VBOOT_VBNV_EC
option.
Remove the VBOOT_VBNV_EC Kconfig option as well as related code, leaving
VBOOT_VBNV_FLASH and VBOOT_VBNV_CMOS as the only two backend options for
vboot nvdata (VBNV).
Also add a check in read_vbnv() and save_vbnv() for VBNV options.
