interconnect changes for 5.7

Here is a pull request with interconnect changes for the 5.7-rc1 merge
window. It contains just driver updates, and these are:

- Refactoring of the SDM845 driver, which is now improved to better
represent the hardware.
- New driver for SC7180 platforms.
- New driver for OSM L3 interconnect hardware found on SDM845/SC7180
platforms.
