Since the struct member .func_conf_select makes the intentions behind it
difficult to ascertain from its name alone, rename it to .get_dbi_offset
to make the intended usage more obvious.

Add R-Car Gen4 PCIe controller support for host mode.
This controller is based on Synopsys DesignWare PCIe. However, this
