Merge patch series "ti: j7: Update to v0.12.0 of DDR config tool"

Neha Malcom Francis <n-francis@ti.com> says:

Update all DDR configuration DTSIs to the latest auto-generated output of
the Sysconfig Tool (DDR Configuration for TDA4x, DRA8x, AM67x, AM68x,
AM69x (0.12.00.0000)) [0]

The auto-generated files must not be modified, but effort will be taken to
change the tool output to adhere to the latest checkpatch.pl rules. J722S
and J721E will also be updated in a subsequent series.

All the changes have been kernel boot tested and memtester has passed (same
as v1, as no functional changes made).

This will need to be explicitly disabled by changing the boot_targets to
disallow fallback during testing.
DDR Configuration
-----------------
The K3 DDRSS driver (drivers/ram/k3-ddrss/k3-ddrss.c) configures the DDR during
the R5 SPL stage. The driver utilizes an auto-generated configuration file
containing necessary settings for the DDR. It configures the frequency, timing
parameters, training algorithms etc. for DDR initialization. The configuration
DTSI can be generated using the `Sysconfig tool <https://dev.ti.com/sysconfig>`_
and selecting the software product as "DDR Configuration for \*" as well as the
required device.
