ARM: dts: OMAP2+: Use pinctrl constants

Using constants for pinctrl allows a better readability, and removes
redundancy with comments.

ARM: dts: omap4-panda: Update the LED support for the panda

The GPIO for LED D1 on the omap4-panda a1-a3 rev and the omap4-panda-es
are different.

A1-A3 = gpio_wk7
ES = gpio_110

There is no change to LED D2

Abstract away the pinmux and the LED definitions for the two boards into
the respective DTS files.

ARM: dts: AM43x: Initial support

DT source (minimal) for AM4372 SoC to represent AM43x SoC's. Those
represented here are the minimal DT nodes necessary to get kernel

In DT nodes, "ti,hwmod" property has not been added, this would be
added along with PRCM support for AM43x.

ARM: dts: omap5: Make uevm as the official board and deprecate sevm support

The uevm is the only official board supported for the OMAP5 soc
in mainline. The existent sevm platform will no more be supported.
Hence cleaning up the board dts file to have only the data
required for uevm.

Renaming the board dts file and adding the following cleanups.

 * There are no devices connected on I2C 2,3,4 buses. So remove
   the pinmux data for the same.

 * OMAP5432 and DDR3 memory is used in the uevm. Temperature polling
   is not supported with DDR3 memories. Because of DDR3 phy limitation
   the voltage change across DVFS and all shadow registers for DVFS on
   DDR3 is not supported. Hence the emif kernel driver is not required,
   so removing the DDR3 device file and emif nodes for uevm.

 * Keypad is not supported on uevm. So remove the device node.

ARM: dts: TWL4030: fix mux and wakeup for SYS_NIRQ line

On most OMAP3 platforms, the twl4030 IRQ line is connected to the
SYS_NIRQ line on OMAP.  Add another DTS include file
(twl4030_omap3.dtsi) for boards that hook up the twl4030 this way
to include.

This allows RTC wake from off-mode to work again on OMAP3-based
platforms with twl4030.  Tested on 3530/Beagle, 3730/Beagle-xM,
3530/Overo, 3730/Overo-STORM.
