PCI: mediatek-gen3: Move controller setup steps before PERST# control

Browse source

Setting up the translation windows and enabling MSI involve only the
controller, not the link or any downstream device. These can be done before
the device is enabled.

Move these steps before the existing PERST# control and waiting for the
link to come up. This provides a cleaner separation of controller vs device
setup. This also allows the later commits that split out PERST# control and
add device power control to have cleaner teardown.

This change only moves code. No functional change is expected.
