AM64 SoC has a single Octal SPI (OSPI) instance under Flash SubSystem
(FSS).  Add DT entry for the same.

Hi Vignesh Raghavendra,

I have applied the following to branch ti-k3-dts-next on [1].
Thank you!

      commit: 81623c55868475c4a81c7cdce38191c92ea37022
[2/2] arm64: dts: ti: k3-am64-evm/sk: Add OSPI flash DT node
      commit: e4e4e89482eafab0774ac0f93dc998eea84e626c

Thanks for rebasing and helping sequence. I have taken note that we
will be converting the binding to yaml in near future, so inline with
what we are doing now, accepting the patches.

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.
