ifdtool: Improve PCH strap handling
Read the PCH Strap Length field in FLMAP1 as described in the
"SPI Programming Guide" and print the number of fields specified there.
This code dumps the following straps:
* Intel GM45: 8 straps
* Intel C216: 72 straps
* Intel C240: 360 straps
Add a new function to easily set PCH straps, which is useful for debugging.
