Merge tag 'omap-for-v5.6/ti-sysc-drop-pdata-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into arm/dt

Drop more legacy platform data for omaps for v5.6 merge window

We can now probe devices with ti-sysc interconnect driver and dts
data, and can continue dropping the related platform data and custom
ti,hwmods dts property for various devices.

And related to that, we finally can remove the legacy sdma support in
favor of using the dmaengine driver only. I was planning to send the
sdma changes separately, but that would have produced a pile of
pointless merge conflicts, so I decided it's best to resolve it locally.
After all, the sdma series also ends up removing the related platform
data.

Note that this series is based on omap-for-v5.6/ti-sysc-dt-signed branch
as it depends for dts data being in place.
