Hi,
Series of patches to cleanup the dts for k2g to sync the dts
with yaml fixups (information provided per patch)
Basic tests performed on k2g-evm. Series has been based on v5.13-rc1 -
will be good to get it in the 5.13 window if possible.

ARM: dts: keystone: k2g: Rename the TI-SCI node
ARM: dts: keystone: k2g: Rename the TI-SCI clocks node name
ARM: dts: keystone: k2g-evm: Move audio oscillator assigned clock to

Rename message-manager instance node name to be better aligned with
current style of device tree nodes for mailboxes.

Lets rename the node name of TI-SCI node to be system-controller as it
is a better standardized name for the function that TI-SCI plays in
the SoC.

We currently use clocks as the node name for the node representing
TI-SCI clock nodes. This is better renamed to being clock-controller
as that is a better representative of the system controller function
as a clock controller for the SoC.

Setting assigned clock with a dependency on itself for k2g_clks
creates a circular dependency. Instead, Lets model the audio clock
as a assigned-clock configuration for mcasp and set it up as the
first clock assigned-clock to be satisfied. Following the standard
convention, we use null entries to indicate entries that doesn't need
to be programmed.
