The GPMC binding is obviously very confusing as the values
are all over the place. People seem to confuse the GPMC partition
size for the chip select, and the device IO size within the GPMC
partition easily.

The ranges entry contains the GPMC partition size. And the
reg entry contains the size of the IO registers of the
device connected to the GPMC.

Let's fix the issue according to the following table:

Device          GPMC partition size     Device IO size
connected       in the ranges entry     in the reg entry

NAND            0x01000000 (16MB)       4
16550           0x01000000 (16MB)       8
smc91x          0x01000000 (16MB)       0xf
smc911x         0x01000000 (16MB)       0xff
OneNAND         0x01000000 (16MB)       0x20000 (128KB)
16MB NOR        0x01000000 (16MB)       0x01000000 (16MB)
32MB NOR        0x02000000 (32MB)       0x02000000 (32MB)
64MB NOR        0x04000000 (64MB)       0x04000000 (64MB)
128MB NOR       0x08000000 (128MB)      0x08000000 (128MB)
256MB NOR       0x10000000 (256MB)      0x10000000 (256MB)

Let's also add comments to the fixed entries while at it.

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.

Special thanks to Florian Vaussard for suggesting use of preprocessor
feature.

Add DT OPP table for OMAP34xx/35xx family of devices. This data is
decoded by OF with of_init_opp_table() helper function.

OPP data here is based on existing opp3xxx_data.c

Since the omap36xx OPP tables would be different from OMAP34xx/35xx,
introduce an new omap34xx.dtsi for 34xx/35xx specific entries and use
existing omap3.dtsi as the common dtsi file for all OMAP3 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 opp3xxx_data.c.
