Features supported in SB700 code:

  * SATA initialization.
  * USB initialization.
  * HDA initialization.
  * LPC initialization.
  * IDE initialization.
  * SMBUS initialization.

Note:
1. I tried to add the description of every step to the code. For example,
   if it is made based on rpr, section 2.4.5, I will pasted the words
   from 2.4.5 to the c code. But the document I worked with might be
   different with the most updated one. A new section has been added and
   the 2.4.5 might be changed to 2.5.5. That migh lead to confusing. I
   correct every comment if I met one. But I have to confess that I am so
   reluctant to find out everyone. I believe it will be correct in the long
   run.
2. I only test the SATA port 0-3. The ports 4, 5 are "PATA emulations".
   I am confused about it.
3. This patch is not only about SB700. Actually it should be
   SB7x0. But I dont think it is nice to change everything to
   SB7x0. It is ugly, isn't it. As far as I know, they all use the
   same code with revision checking. If you guys think it is
   appropriate, please modify it to sb7x0.
