vboot: add vbnv flash driver
this adds a driver for vboot to read and write nvdata in spi flash.
it's assumed that flash contents are erased to 1-bits and write
operations can only change 1-bits to 0-bits.
when all nvram space is used, the driver will erase the whole block
and start the next write from the beginning.
