PCI: designware: Check for iATU unroll only on platforms that use ATU
Previously we checked for iATU unroll support by reading PCIE_ATU_VIEWPORT even on platforms, e.g., Keystone, that do not have ATU ports. This can cause bad behavior such as asynchronous external aborts: OF: PCI: MEM 0x60000000..0x6fffffff -> 0x60000000 Unhandled fault: asynchronous external abort (0x1211) at 0x00000000 pgd = c0003000 [00000000] *pgd=80000800004003, *pmd=00000000 Internal error: : 1211 [#1] PREEMPT SMP ARM Modules linked in: CPU: 0 PID: 1 Comm: swapper/0 Not tainted 4.9.0-00009-g6ff59d2-dirty #7 Hardware name: Keystone task: eb878000 task.stack: eb866000 PC is at dw_pcie_setup_rc+0x24/0x380 LR is at ks_pcie_host_init+0x10/0x170 Move the dw_pcie_iatu_unroll_enabled() check so we only call it on platforms that do not use the ATU. These platforms supply their own ->rd_other_conf() and ->wr_other_conf() methods.
