To deprecate VBOOT_VBNV_CMOS [1], replace VBOOT_VBNV_CMOS with
VBOOT_VBNV_FLASH for boards using SOC_INTEL_BRASWELL.
Currently BOOT_DEVICE_SPI_FLASH_NO_EARLY_WRITES is selected for
CPU_INTEL_HASWELL, SOC_INTEL_BRASWELL and others (see [2]). However,
there seems to be no particular reason on those platforms. We've dropped
the config for haswell. Now do the same for SOC_INTEL_BRASWELL, so that
VBOOT_VBNV_FLASH can be enabled.
VBOOT_VBNV_FLASH is enabled for the following boards:
- facebook/fbg1701: A 0x2000 RW_NVRAM region is allocated, with the
FW_MAIN_A(CBFS) size reduced by 0x2000.
- google/cyan, intel/strago: Repurpose RW_UNUSED as RW_NVRAM.

Contents of unsigned AMDFW in RW sections are verified twice in PSP
verstage - first time by vboot verifying the firmware body, second time
by CBFS verification while the file is loaded to update PSP about the
boot region. This redundant verification adds to boot time. Minimize the
redundancy by splitting the EFS header from the AMDFW body and keep them
as 2 separate CBFS files. This helps to improve the boot time by another

This patch avoids hardcoding to the `use_eisa_hids` variable instead
relying on the SoC config to choose if the SoC platform supports
EISA HID.
If any SoC platform has the support then the `use_eisa_hids` variable
would be set to `true` based on the selection of `DPTF_USE_EISA_HID`
config.
Note: Prior to Tiger Lake, all DPTF devices used 7-character EISA
IDs. If selected, the 7-character _HIDs will be emitted,
otherwise, it will use the "new" style, which are regular
8-character _HIDs.
Ideally, the platform prior to Tiger Lake would set `use_eisa_hids`
to `true` and platform posts that would set `use_eisa_hids` to
`false`.

the vboot before a FW slot is selected.
