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.
