{MTD] add support for Intel's "Sibley" flash
This updates the Primary Vendor-Specific Extended Query parsing to version 1.4 in order to get the information about the Configurable Programming Mode regions implemented in the Sibley flash, as well as selecting the appropriate write command code. This flash does not behave like traditional NOR flash when writing data. While mtdblock should just work, further changes are needed for JFFS2 use.
