Certain revisions of the TI EMIF IP contain ECC support in them. Reflect
this in the DT binding. Also, add interrupts property as a required
property for the emif controller, as all revisions of the emif IP contain
interrupt support; this might remain unused by the kernel driver though.

Improve the binding example by removing all the leading 0x to fix the
following dtc warnings:
Warning (unit_address_format): Node /XXX unit name should not have leading "0x"
Converted using the following command:
find Documentation/devicetree/bindings -name "*.txt" -exec sed -i -e 's/([^ ])\@0x([0-9a-f])/$1\@$2/g' {} +
This is a follow up to commit 48c926cd3414

Update the Texas Instruments EMIF binding document to include the device
tree bindings for ti,emif-am3352 and ti,emif-am4372 which are used by
the ti-emif-sram driver to provide low-level PM functionality.

On am33xx we're missing the pmu and emif nodes with their related
"ti,hwmods" properties that the SoC interconnect code needs.
Note that this will only show up as a bug with "doesn't have
mpu register target base" boot errors when the legacy platform
data is removed.
Let's also update the related binding documentation while at it.

Add node for TI AM4372 EMIF. Without this we get a warning with the
recent commit fabbe6df (ARM: OMAP: AM43xx hwmod: Add data for am43xx
emif hwmod).

EMIF - External Memory Interface - is an SDRAM controller used in
TI SoCs. EMIF supports, based on the IP revision, one or more of
DDR2/DDR3/LPDDR2 protocols. This binding describes a given instance
of the EMIF IP and memory parts attached to it.
