vboot: Introduce kconfig variable for VBNV backing storage
This introduces a new kconfig variable to select the VBNV backing
store explicitly instead of inferring it from CPU/SoC architecture.
x86 platforms have historically relied only on CMOS to store VBNV
variables, while ARM-based platforms have traditionally relied on
the EC. Neither of those solutions are going to scale well into
the future if/when CMOS disappears and we make ARM-based systems
without an EC.
