The non-DM version of this driver used to set BAR0 register after the
calls to pci_set_region.
I found out that for some strange reason the ath10k driver in kernel
fails to work if this is done the other way around.
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.

Use the uclass_first_device_check and uclass_next_device_check functions
instead of uclass_first_device and uclass_next_device in pci_init. This
ensures that all PCI devices are tried to be probed. Currently if a
device fails to probe, the enumeration stops and the devices which come
after the failed device are not probed.
