Refine Flash Component descriptor handling
Possible values as well as encodings have changed in newer chipsets as follows.
- Pre-PCH (i.e. ICH) chipsets had a maximum frequency of 33 MHz for all
operations
- Since Cougar Point the chipsets support dual output fast reads (encoded
in bit 30).
- Flash component density encoding has changed from 3 to 4 bits with Lynx
Point, currently allowing for up to 64 MB chips.
Corresponding to flashrom svn r1843.
