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.

The bootloader configures the pins, but has pull bits
set without pull enable bits. While this is harmless,
and won't do anything, it seems to cause confusion at
least for me every time looking at the pin configuration.
Fix it for DT based boot.

Commit ff5c9059 (ARM: dts: OMAP3+: Correct gpio #interrupts-cells
property) updated the number of interrupt cells required for configuring
gpios as interrupts for other devices (such as ethernet controllers).
This update allowed the interrupt type (edge, level, etc) to be
configured via device-tree (as described in the
Documentation/devicetree/bindings/gpio/gpio-omap.txt).

This broke ethernet support on the OMAP4 SDP board that defines a gpio
as the ethernet IRQ because the interrupt type (level, edge, etc) was
not getting configured correctly. This board use the ks8851 ethernet
chip which has an active low interrupt. Fix this by defining the gpio
interrupt as active-low in the device-tree binding.

Please note that the OMAP4-VAR-SOM also uses the same ethernet
controller and it is expected it will have the same problem. So the
same fix is also applied to this board.

Add DT OPP table for OMAP443x family of devices. This data is
decoded by OF with of_init_opp_table() helper function.

OPP data here is based on existing opp4xxx_data.c

Since the omap4460 OPP tables would be different from OMAP443x,
introduce an new omap443x.dtsi for 443x specific entries and use
existing omap4.dtsi as the common dtsi file for all OMAP4 platforms.

This is in preparation to use generic cpufreq-cpu0 driver for device
tree enabled boot. Legacy non device tree enabled boot continues to
use omap-cpufreq.c and opp4xxx_data.c.
