We can now probe devices with device tree only configuration using
ti-sysc interconnect target module driver. Let's configure the
module, but keep the legacy "ti,hwmods" peroperty until the child
devices are probing with ti-sysc interconnect driver.
The display subsystem (DSS) is in a 16MB interconnect target module
mapped to l4 and l3 buses. We are only using the l3 port as recommended
by the TRM. So there is no need to configure l4 ranges like we've done
for l4 ABE instance for example.
Initially let's just update the top level dss node to probe with ti-sysc
interconnect target module driver. The child nodes are still children
of dispc, only the node indentation changes for them now along with
using the reg range provided by top level dss.
Let's also add add a note about using only the l3 access without l4
as noted in the TRM.

Add RNG interconnect data for omap4 similar to what dra7 has. The
clock is OMAP4_CM_L4SEC_RNG_CLKCTRL_OFFSET at offset address 0x01c0,
which matches what dra7 also has with DRA7_L4SEC_CLKCTRL_INDEX(0x1c0).
Note that we need to also add the related l4_secure clock entries.
I've only added RNG, the others can be added as they get tested.
They are probably very similar to what we already have for dra7
in dra7_l4sec_clkctrl_regs[].
With the clock tagged CLKF_SOC_NONSEC, clock is set disabled for secure
devices and clk_get() will fail. Additionally we disable the RNG target
module on droid4 to avoid introducing new boot time warnings.

While reviewing the missing mcasp ranges I noticed omap4 hsi range
for gdd is wrong so let's fix it.
I'm not aware of any omap4 devices in mainline kernel though that use
hsi though.

With l4 interconnect hierarchy and ti-sysc interconnect target module
data in place, we can simply move all the related child devices to
their proper location and enable probing using ti-sysc.
In general the first child device address range starts at range 0
from the ti-sysc interconnect target so the move involves adjusting
the child device reg properties for that.
And we cannot yet move mmu_dsp until we have a proper reset controller
driver for rstctrl registers.
In case of any regressions, problem devices can be reverted to probe
with legacy platform data as needed by moving them back and removing
the related interconnect target module node.

Let's add proper interconnect hierarchy for l4 interconnect
instances with the related ti-sysc interconnect module data as
documented in Documentation/devicetree/bindings/bus/ti-sysc.txt.
Using ti-sysc driver binding allows us to start dropping
legacy platform data in arch/arm/mach-omap2/omap*hwmod*data.c
files later on in favor of ti-sysc dts data.
For setting up a proper hierarchy for the interconnect and
ti-sysc data, there are multiple reasons:
1. We can use dts ranges to protect registers from being
ioremapped from other devices and prevent hard to track
issues with failed flush of posted write between modules
2. Some of the ranges may not be accessible to operating systems
at all if configured so on high-security devices
3. The interconnect hierarchy provides proper clockdomain
hierarchy that can be used for genpd later on
4. We can avoid almost all deferred probe related issues simply
by probing the resource providing interconnect instance first
for l4 wkup instance
5. With deferred probe issues gone, we can probe everything
later at module_init time except for system timer and interrupt
controller and their clocks.
This data is generated based on platform data from a booted system
and the interconnect acces protection registers for ranges. To avoid
regressions, we initially validate the device tree provided data
against the existing platform data on boot.
Each interconnect instance is typically divided into segments
to avoid powering up the whole interconnect. And each segment
has one or more ranges TI specific interconnect target modules
connected to it. Some devices can also have a separate data
access port directly to the parent L3 interconnect for DMA that
can be set up as a separate range.
Note that we cannot yet include this file from omap4.dtsi
until child devices are moved to their proper locations in
the interconnect hierarchy in the following patch. Otherwise
we would have the each module probed twice.
Also note that this does not yet add l4 abe instance, that will
be added separately later on.
