vboot/vbnv_flash: make I/O connection agnostic
There's no need to be SPI specific w.r.t. how the flash is
connected. Therefore, use the RW boot device to write the
contents of VBNV. The erasable check was dropped because that
information isn't available. All regions should be aligned
accordingly on the platform for the underlying hardware
implementation. And once the VBNV region fills the erase
will fail.
