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.

Add d_can instances to aliases node to get the D_CAN instance number
from the driver. To initialize D_CAN message RAM, corresponding instance
number is required.
To initialize instance 0 message RAM then 0x1 should be written and for
instance 1 message RAM, 0x2 should be written to control module register.
With device-tree framework ip instance number is "-1" by default for all
instances. To get device id/instance number then modules should be added
to DT "aliases" node. of_alias_get_id() gives the device id number based
on number of alias nodes present in "aliases node".

Since AM33XX supports only DT-boot, this is needed
for the appropriate device nodes to be created.
Note: OCMC RAM is part of the PER power domain and supports
retention. The assembly code for low power entry/exit will
run from OCMC RAM. To ensure that the OMAP PM code does not
attempt to disable the clock to OCMC RAM as part of the
suspend process add the no_idle_on_suspend flag.

The interrupt-parent attribute does not have to be added in each
node since the fmwk will check for the parent as well to get it.

The device/node resources (like, IORESOURCE_MEM and IORESOURCE_IRQ)
are overwritten by hwmod resources, due to all known reasons but
that should not be the reason for not providing all the information
in the DTS blob. Ideally we should use DTS resource and use HWMOD
framework wherever required and for only specific things.
Newer platforms like, OMAP5 and AM33XX, we only support DT boot mode,
so this patch is preparation for the future where we supposed to get
rid of hwmod dependency anyway.

Ideally in common SoC dtsi file should set all modules

This patch sets default status of all modules to "disabled"
state in am33xx.dtsi file. Currently there are no modules
supported as part of Bone and EVM dts support, so care
to add entry "status = "okay"" while adding support for any
module.
