Currently on Keystone SoCs, boot up log shows an unnecessary boot
noise as follows:-
[ 0.365823] keystone-pcie 21021000.pcie: missing *config* reg space
Keystone uses older version of designware h/w 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).
So add a check to avoid this boot noise on Keystone.
