I was little bit too enthusiastic about it :( To enable PCI on Harmony and
probably on Ventana one need to have I2C and TPS up and running before setting
up the PCI clocks...
I have working implementation on top of your  linux-tegra-2.6.37 branch (1), but
it's not quite ready to go upstream.

So, let's keep the TrimSlice out of common defconfig for now
