Add DT OPP table for OMAP36xx/37xx family of devices. This data is

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.

The binding documentation for the OMAP GPIO controller has the
"#interrupt-cells" property listed before "#interrupt-controller"
property but its description after.
This is confusing so we move "#interrupt-cells" after the
"interrupt-controller" property so is followed by its description.

While being there, change the properties order to be consistent with
Documentation/devicetree/bindings/interrupt-controller/interrupts.txt
and Documentation/devicetree/bindings/gpio/gpio.txt.

According with these docs, the order of the properties for a gpio-omap
device node should be:

    gpio-controller;
    #gpio-cells = <2>;
    interrupt-controller;
    #interrupt-cells = <2>;

OMAP hwmod layer does the reset of the IPs in early code so that
we have SOC in sane state. To do the soft-reset, it needs to ioremap()
the IP address space to be able to write to sysconfig registers.

But there are few hwmod which doesn't have sysconfig registers and hence
no need to ioremap() them in early init code.

Prevent calling the _init_mpu_rt_base() conditional based on sysc
availability.

The OMAP gpio binding documention [1] states that the #interrupts-cells
property for gpio controllers should be 2. Currently, for OMAP3+ devices
the #interrupt-cells is set to 1. By setting this property to 2, it
allows clients to pass a 2nd parameter indicating the sensitivity (level
or edge) and polarity (high or low) of the interrupt. The OMAP gpio
controllers support these options and so update the #interrupt-cells
property for OMAP3+ devices to 2.

Currently the OMAP General-Purpose Memory Controller (GPMC) device
node maps 16 MB of address space for its hardware registers.

This is because the OMAP Technical Reference Manual says that the
GPMC module register address space size is 16 MB. But in practice
the maximum address offset used by a GPMC register is 0x02d0.

So, there is no need to map such a big address space for GPMC regs.

This change was suggested by Jon Hunter [1].
