Subject: ARM: OMAP3+: PRM: add common APIs for prm_vp_check/clear_txdone

PRM driver now only exports a generic API for clearing / checking
VP txdone status.

Subject: ARM: OMAP4+: PRM: move omap_prm_base_init under OMAP4 PRM driver

There is no need to call this separately from io.c, rather this can be
done commonly under the PRM driver.

Subject: ARM: OMAP2+: PRM: determine PRM base address from device tree

There is no need to provide the PRM base address through a low-level API
from the low-level IO init, as this information is available through DT.
Re-routed the parsing function to be called from the PRM drivers also to
simplify the implementation under io.c.

Subject: ARM: OMAP2+: PRM: move SoC specific init calls within a generic API

This gets rid of need for some exported driver APIs, and simplifies the
initialization of the PRM driver. Done in preparation to make PRM a
separate driver. The init data is now also passed to the SoC specific
implementations, allowing future expansion to add feature flags etc.

From 48e0c1148d18de677f1b2aec179f36fb7c1e3839 Mon Sep 17 00:00:00 2001
From: Tero Kristo <t-kristo@ti.com>
Date: Mon, 8 Sep 2014 11:29:43 +0300
Subject: ARM: OMAP4+: PRM: determine prm_device_inst based on DT compatibility

PRM device instance offset is now provided through the prm_init_data.
This gets rid of some cpu_is_X / soc_is_X calls from PRM core code,
preparing for PRM to be its own separate driver.

Subject: ARM: OMAP4+: PRM: setup prm_features from the PRM init time flags

Currently some cpu_is_X checks are used to setup prm_features, however
the same can be accomplished by just passing these flags from the PRM
init data. This is done in preparation to make PRM a separate driver.

Subject: ARM: OMAP4+: PRM: get rid of cpu_is_omap44xx calls from interrupt
 init

The compatible DT node is now passed with the prm init, so there is no
need to do node matching here again. Added a new flag to the init data
also, to detect default IRQ support for OMAP4. Also, any booting omap4
DT setup always has a PRM node, so there is no need to check against
the special case where it would be missing.
