PCI: designware: Make config accessor override checking symmetric
Drivers based on the DesignWare core can override the config read accessors
by supplying rd_own_conf() and rd_other_conf() function pointers.
dw_pcie_rd_conf() calls dw_pcie_rd_own_conf() (for accesses to the root
bus) or dw_pcie_rd_other_conf():
dw_pcie_rd_conf
dw_pcie_rd_own_conf # if on root bus
dw_pcie_rd_other_conf # if not on root bus
Previously we checked for rd_other_conf() directly in dw_pcie_rd_conf(),
but we checked for rd_own_conf() in dw_pcie_rd_own_conf().
Check for rd_other_conf() in dw_pcie_rd_other_conf() to make this symmetric
with the rd_own_conf() checking, and similarly for the write path.
No functional change intended.
