The ath79_device_reset_* are causing BUG when
those are used on the QCA955x SoCs. The patch
adds the required code to avoid that.

/proc/vmcore wasn't showing up in kdump kernels.  It turns that that
for Octeon, the memory used by elfcorehdr wasn't being set aside
properly and it was getting clobbered before /proc/vmcore could get
it.  So reserve the memory if it shows up in a memory area managed
by the kernel.

The IO and memory resources of a PCI controller
might already have a parent resource set when
they are passed to 'register_pci_controller'.

If the parent resource is set, the request_resource
call will fail due to resource conflict and the
current code will not be able to register the
PCI controller.

Use the parent resource if it is available in the
request_resource call to avoid the isssue.
