We can now drop legacy init for sdma as we pass the quirks in auxdata to
the dmaengine driver.

We can populate the legacy resources needed by dma and smartreflex
from device tree in omap_device_build().
There should be no need to do this for other devices, and eventually
these two remaining users will be gone too. The legacy dma will be
dropped when the remaining users have been converted to use the
dmaengine driver, and smartreflex can now become just a regular
device driver with a few pdata callbacks.
This is needed in order to remove remaining device dma, irq and io
resources from the interconnect code.
And while at it, let's simplify things by removing otherwise
unused omap_device_build_ss() as we will never call it for more
than one hwmod.

Due to the cross dependencies between hwmod for automanaged device
information for OMAP and dts node definitions, we can run into scenarios
where the dts node is defined, however it's hwmod entry is yet to be
added. In these cases:
a) omap_device does not register a pm_domain (since it cannot find
hwmod entry).
b) driver does not know about (a), does a pm_runtime_get_sync which
never fails
c) It then tries to do some operation on the device (such as read the
revision register (as part of probe) without clock or adequate OMAP
generic PM operation performed for enabling the module.
This causes a crash such as that reported in:
https://bugzilla.kernel.org/show_bug.cgi?id=66441
When 'ti,hwmod' is provided in dt node, it is expected that the device
will not function without the OMAP's power automanagement. Hence, when
we hit a fail condition (due to hwmod entries not present or other
similar scenario), fail at pm_domain level due to lack of data, provide
enough information for it to be fixed, however, it allows for the driver
to take appropriate measures to prevent crash.

Remove "no_idle_on_suspend" check, since respective
driver should be able to prevent idling of an
omap device whenever required.
Driver's can get same behavior by just returning -EBUSY
from their ->runtime_suspend only during suspend.

Remove now-obsolete code from arch/arm/mach-omap2/omap_device.c. This
mostly consists of removing the first attempt at device PM latency
handling. This was never really used, has been replaced by the common
dev_pm_qos code, and needs to go away as part of the DT conversion.
Also, the early platform_device creation code has been removed, as it
appears to be unused.

Let's make omap_hwmod local to mach-omap2 for
ARM common zImage support.
