Merge tag 'omap-for-v5.10/ti-sysc-drop-pdata-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into arm/soc

Add initial genpd support for omaps to drop more platform data

We now drop legacy platform data for RTC on am3, am4 and dra7.
And we add initial genpd support for PRM (Power and Reset Manager)
and use it to drop legacy platform data for am3 sgx and omap4/5
l4_abe interconnect instance.
