Wrong CFI offset in cfi_cmdset_0001.c

[Jared Hulbert]

Sorry. It took me longer than it should have to track down a P30 part
and get it on my machine.  Does this work for you?

Is this format ok?

[MTD] CHIPS: fix for P30 cfi parsing

Change to the extended cfi table parsing for Intel NOR flash that uses
the info in the extended table to 'walk' the table rather than using
hard coding for various primary extended query table version numbers.
