The dw_pcie_host_init() method has two instances of the resource structure
pointers used in non-related places of the method. It's pointless to have
two different local storages for them since the corresponding code is
small and having resource specific names doesn't make it more readable.
Let's convert these parts of the function to using just a common pointer
to the resource structure instance. That shall make the code a bit nicer
looking.
