[PATCH] i2c-i801: Fix resume when PEC is used

Fix for bug #6395:

Fail to resume on Tecra M2 with ADM1032 and Intel 82801DBM

The BIOS of the Tecra M2 doesn't like it when it has to reboot or resume
after the i2c-i801 driver has left the SMBus in PEC mode.  The most simple
fix is to clear the PEC bit after after every transaction.  That's what
this driver was doing up to 2.6.15 (inclusive).

Thanks to Daniele Gaffuri for the very good report.
