Commit '3b9b1015' cleaned up the
data file to remove all irq and dma entries for all hwmods, which
are now populated by DT. But mcspi and mmc irq, dma entries were
retained since MMC, NFS boot was not working. Since it is root caused
to be an issue with only DMA entries [1], irq can be safely removed.

Commit 3b9b1015 (ARM: OMAP4: hwmod data:
Clean up the data file) removes hwmod data for omap4, including DSS
data. DSS has not yet been converted to DT, so the hwmod data is still
needed.

This patch adds back the DSS parts of the hwmod data.

- The IO resource information like dma request lines, irq number and
  ocp address space can be populated via dt blob. So such data is stripped
  from OMAP4 SOC hwmod data file.

- The devices which are still missing the device tree bindings,
  address space entries are not removed yet. When such devices add
  the dt bindings, respective address space data can be deleted.

- Also other unnecessary hwmods like firewalls are removed as a part of this.
  Since emif was getting registered only because of this firewalls links,
  the mpu->emif direct link is added now.

The above update, results in reduction of about ~1650 lines of code.

AM33XX only supports DT boot mode and with addition of
extracting module resources like, irq, dma and address space
from DT block, so now we can remove duplicate information from
hwmod data file.

This patch cleanups-up/deletes,

     - All references to "omap_hwmod_irq_info" data.
     - All references to "omap_hwmod_dma_info" data.
     - References to "omap_hwmod_addr_space" of the modules
       for which DT node is available with required address
       space information.
     - For the modules where "sysc" field is not applicable,
       we don't need module address space, so remove them as well.
     - The hwmod like firewall etc which are not useful are also
       deleted.

This cleanup gets us around ~1100 LOC of negative diff.
Patch is boot tested on AM335x-EVM along with below modules -
	- Matrix-keypad
	- Volume up/down keys
	- Ethernet
	- RTC

Earlier commits ensured proper muxing of pins related to proper
TWL6030 behavior: see commit 265a2bc8 (ARM: OMAP3: TWL4030: ensure
sys_nirq1 is mux'd and wakeup enabled) and commit 1ef43369 (ARM:
OMAP4: TWL: mux sys_drm_msecure as output for PMIC).

However these only fixed legacy boot and not DT boot.  For DT boot,
the default mux values need to be set properly in DT.

Special thanks to Nishanth Menon for the review and catching some
major flaws in earlier versions.

Tested on OMAP4430/Panda and OMAP4460/Panda-ES.

We can now boot with device tree. If you don't want to update u-boot,
you can boot with appended DTB with the following instructions:

1. Make sure you have the appended DTB support in .config

   CONFIG_ARM_APPENDED_DTB=y
   CONFIG_ARM_ATAG_DTB_COMPAT=y
   CONFIG_ARM_ATAG_DTB_COMPAT_CMDLINE_EXTEND=y

2. Build the zImage

   $ ARCH=arm CROSS_COMPILE=... make zImage

3. Build the device tree blobs

   $ ARCH=arm CROSS_COMPILE=... make dtbs

4. Append the correct panda dtb to zImage

   Depending on your hardware it's omap4-panda.dtb, omap4-panda-a4.dtb
   or omap4-panda-es.dtb.

   $ cat arch/arm/boot/zImage arch/arm/boot/dts/omap4-panda-es.dtb > /tmp/appended

5. Use mkimage to produce the appended device tree uImage

   $ mkimage -A arm -O linux -T kernel -C none -a 0x80008000 -e 0x80008000 \

Commit a819c4f1 (ARM: OMAP3: PM: Only access IVA if one exists)
changed PM to not access IVA registers on omaps that don't have
them. Turns out we still need to idle iva2 as otherwise
iva2_pwrdm will stay on and block deeper idle states.

It seems that the only part of the reset that may not be needed
is the setting of the iva2 boot mode to idle. But as that register
seems to be there and is harmless if no iva2 is on the SoC, it's
probably safest to do the complete reset.

* CYAPA trackpad driver
* simplefb
* CROS EC and keyboard drivers
* S5M8767 driver
* MAX77686 drivers
* MAX8997 driver
* DEVTMPFS + mount
* DM_CRYPT (as module)
* CRYPTOLOOP
