Subject: [PATCH v2 0/4] drivers: net: cpsw: fix driver loading/unloading

This series fixes set of isssues observed when CPSW driver module is unloaded/loaded:
1) rmmod: deadlock in cpdma_ctlr_destroy
2) rmmod: L3 back-trace and crash if all net interfaces are down, because CPSW
can be powerred down by PM runtime in this case.
3) insmod: mdio device is not recreated on next insmod
 - need to use of_platform_depopulate() in cpsw_remove().
4) rmmod: system crash on omap_device removal

Tested on: am437x-idk, am57xx-beagle-x15

Changes in v2:
- build warning fixed
- added fix for correct omap_device removal
