mb/lenovo/t60: Remove PCI reset code from romstage 

Commit bf264e94 (i945:) adds a PCI reset to the romstage, and commit
bc8613ec (Fix i945 based boards) fixes that to use the correct
delay of 200 ms. This code was then copied over, when adding support for
the Lenovo T60.

The reset was related to the shipped crypto card on the Roda RK886EX and
Kontron 986LCD-M, so is not needed on the Lenovo T60. So remove it, to
reduce the boot time by 200 ms.

The same change is done for the Lenovo X60 in commit 7676730b
(mb/lenovo/x60: Remove PCI reset code from romstage).
