Maybe, but I guess more correct is to deal with USB->PCI dependency..
Is it really needed(I am not USB expert)?

Neither am I. I guess for this Host Controler it is not needed at
HW level, but I am not sure why it is still required by the SW.

3) I have seen that from u-boot, a reset occurs when I read Internal
Memory at offset 0x10904 (PCI CFG_DATA). From BDI, when I do the same
all PCI section on IM becomes zero. Is this a known behaviour? May this
reflect a hardware problem?

Sounds weird

Here is the problem. The cause for this weird behaviour is that I
had PCI_ARBITER_EN_  disabled. So, a HW problem at the end.
I had disabled it trying to reduce power compsumption due to the PCI,
as I am not going to use it. It seems it is not possible that way.
Any idea how to get this done?

I'm guessing you dont have anything else doing arbitration on the bus.
