[PATCH v2] arm64: dts: ti: k3-j721e-common-proc-board: Enable OSPI1 on J721E

[Prasanth Babu Mantena]

J721E SoM has MT25QU512AB Serial NOR flash connected to
OSPI1 controller. Enable ospi1 node in device tree.

Yes, cb27354b38f3b ("arm64: dts: ti: k3-j721e: Add DT nodes for few
peripherials") did not enable the node, But back then, we used to
ensure all nodes were left default (okay) and then disable unused
nodes in board dts.

BUT, we ended up having a bunch of maintenance issues and board bring
up problems and looking at the rest of the ARM ecosystems (you can
check the mailing list for all the discussions on the topic), we
flipped the order for peripherals that need board level connectivity
for functionality to be disabled in SoC.dtsi and enabled explicitly at
board level and when that occurred, specifically:
73676c480b72 ("arm64: dts: ti: k3-j721e: Enable OSPI nodes at the board
level") which enabled ospi0 at SoM level, but missed fixing this up,
whoops!

I will fix this up locally when I apply this patch. but FYI.

I have applied the following to branch ti-k3-dts-next on [1].
I have done a minor local fixup for Fixes tag as I had responded
in the thread.
Thank you!

      commit: 6b8deb2ff0d31848c43a73f6044e69ba9276b3ec

All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent up the chain during
the next merge window (or sooner if it is a relevant bug fix), however if
problems are discovered then the patch may be dropped or reverted.

You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.

If any updates are required or you are submitting further changes they
should be sent as incremental updates against current git, existing
patches will not be replaced.

Please add any relevant lists and maintainers to the CCs when replying
to this mail.
