Enable VBOOT_VBNV_FLASH for SOC_INTEL_BRASWELL
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.
