Late changes for omap secure accelerators for v5.6 merge window

A series of changes to configure secure accelerators for omap4 & 5
to finally get hardware random number generator working.

Apologies on a late pull request on these changes, but this pull
request could not be sent out earlier because of a dependency to
recent clock changes. This is based on earlier changes to drop omap
legacy platform data with Tero Kristo's for-5.6-ti-clk branch merged
in.
