interconnect changes for 5.20
Here are the interconnect changes for the 5.20-rc1 merge window consisting
of two new drivers, misc driver improvements and new device managed API.
Core change:
- Add device managed bulk API
Driver changes:
- New driver for NXP i.MX8MP platforms
- New driver for Qualcomm SM6350 platforms
- Multiple bucket support for Qualcomm RPM-based drivers.
