uclass_first_device/uclass_next_device return value will be removed,
don't use it.

With the current implementation dev is equivalent to !ret. It is
redundant to check both, ret check can be replaced with dev check, and
ret check inside the iteration is dead code.

PCIe config space has address range 0-4095. So do not allow reading from
addresses outside of this range. Lot of U-Boot drivers do not expect that

ignores return value.

The behaviour of the function is changed such that they don't

Writing to the PCI_PRIMARY_BUS register of the root port should not change

This PCI_PRIMARY_BUS register is used only for correct configuration of
legacy PCI stuff, like forwarding of PCI special cycles between buses.

Aardvark HW does not support PCI special cycles, so it does not have HW
register for PCI_PRIMARY_BUS and therefore it does not matter what is
stored in this register.

So fix this issue and do not use PCI_PRIMARY_BUS register in pci-aardvark.c

After this change there is no reason for storing bus number (zero) into
first_busno variable, so remove this variable.
