fw update: spi device code updater

This code updater is for updating spi flash devices.
It can for example update the host firmware on different server boards
and has following features:

- power down the host before update
- set mux gpios to access spi flash
- (very limited) communication with ME (Management Engine)
- use flashrom to utilize fw with IFD (Intel Flash Descriptor)
- otherwise directly write to the flash chip.

The behavior of this code updater can be configured via EM.

Tested: on Tyan S5549 Board
