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.

Add PMU nodes for OMAP2, OMAP3 and OMAP4460 devices.

Please note that the node for OMAP4460 has been placed in a separate
header file for OMAP4460, because the node is not compatible with
OMAP4430. The node for OMAP4430 is not included because PMU is not
currently supported on OMAP4430 due to the absence of a cross-trigger
interface driver.

If device-tree is present, then do not create the PMU device from within
the OMAP specific PMU code. This is required to allow device-tree to
create the PMU device from the PMU device-tree node.

PMU is not currently supported for OMAP4430 (due to a dependency on
having a cross-trigger interface driver) and so ensure that this
indicated on boot with or without device-tree.

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].

Add a new address space/memory resource to d_can device tree node. D_CAN
RAM initialization is achieved through RAMINIT register which is part of
AM33XX control module address space. D_CAN RAM init or de-init should be
done by writing instance corresponding value to control module register.

Till we have a separate control module driver to write to control module,
d_can driver will handle the register writes to control module by itself.
So a new address space to represent this control module register is added
to d_can driver.
