RFC: tentative additions to fix ABE/AESS device tree entries

This is part of a bigger project to provide a modern driver for the
OMAP4/5 Audio Engine (ABE/AE/AESS). The first step is to fix/add some
device tree records so that this allows to do power and clock management
by a driver and give the processor access to all interface registers
and memory blocks.

Main RFC question is if clock setup is correct. For example there is
no connection to abe_giclk_div / ocp_abe_iclk / abe_iclk.

Notes:
- this may be extensible to DRA7xx
- code is based on v6.5
- there is no bindings document for ti,omap4-aess
