I found out that for some strange reason the ath10k driver in kernel

I know that Linux's driver should not depend on how U-Boot does things,
but for some strange reason it does and this seems to be the simplest
solution. Fix it since it caused regressions on Omnia.

This fix issue when access config from PCIe switch.

The PCIe controller need to send Type 0 config TLP if the targeting bus
matches with the secondary bus number, which is when the TLP is targeting
the immediate device on the link.

The PCIe controller send Type 1 config TLP if the targeting bus is
larger than the secondary bus, which is when the TLP is targeting the
device not immediate on the link.
