PCI: designware: Don't complain missing *config* reg space if va_cfg0 is set
Currently on Keystone SoCs, we always complain:
keystone-pcie 21021000.pcie: missing *config* reg space
Keystone uses an older version of DesignWare hardware that doesn't have
ATU support. So va_cfg0_base and va_cfg1_base are already set up in
ks_dw_pcie_host_init() before calling dw_pcie_host_init(), and they point
to the remote config space address va (both same for Keystone). Add a
check to avoid this boot noise on Keystone.
