[PATCH] k3-am68: Sync from Linux tag v6.6-rc1

19 Sep 2023

The following commit syncs the device tree from Linux tag
v6.6-rc1 to U-boot and fixes the following to be compatible with
the future syncs -
- Include k3-am68-sk-base-board.dts file
Remove the duplicated pinmuxes from r5 and -u-boot.dtsi files and
    include k3-am68-sk-base-board.dts for Linux fixes to propagate
    to U-boot.
- Fixing the mcu_timer0
Remove timer0 and use the mcu_timer0 defined in mcu-wakeup.dtsi
- Fixing secure proxy nodes
Linux DT now have these nodes defined so remove them and rename to
    use the Linux DT ones.
- Remove cpsw node
The compatible is now fixed and the node is not required in
    -u-boot specifically
- Remove aliases and chosen node
Use these from Linux and don't override when not required.
- Remove /delete-property/ from sdhci nodes
We have the necessary clock and dev data so remove these.
- Remove dummy_clocks and fs_loader0
These weren't being used anywhere so remove it.
- Remove mcu_ringacc override
All these have been put in a single commit to not break the
bisectability.
