Hi,

Series adds hotplug support for the rzg3s-host driver. This is a
continuation of the series John posted initially at [1]. Along with it,
prerequisites fixes and cleanup patches were added.

Series applies on top of [2].

Thank you,
Claudiu

Changes in v4:
- simplified comments in patch 2/8
- kept only DL_UpDown changes in patch 7/8
- added patch 8/8 for the .reset_root_port() support

Changes in v3:
- added patches 1-6
- re-worked patch 7 to use struct pci_host_bridge::reset_root_port() API
