v1 - v2 : Fixed the issue with Patch 5. In v1 it was not calling
sw_babble_control().

resetting the IP block. In preperation to add that support
its better to have a rest_done return for musb_platform_reset().

With this I think it make sense to take the following patch also, to
avoid unnecessary probe deferral

so it's probed first.

The series does some refactoring on dwc3_probe()
Patch 1-3 - reduce the size of dwc3_probe()
Patch 4 - Fix the crash on dwc3_omap removal
Patch 5 - Addresses the issue of xhci hang while resuming from system sleep.

Find whether we are running on newer silicon. The babble control
register reads 0x4 by default in newer silicon as opposed to 0
in old versions of AM335x. Based on this enable the sw babble
control logic.
