[PATCH v4 3/3] ARM: dts: aspeed-g6: Add nodes for i3c controllers

[Dawid Glazik <dawid.glazik@linux.intel.com>]

Add the i3c controller devices to the ast2600 g6 common dts. We add all
6 busses to the common g6 definition, but leave disabled through the
status property, to be enabled per-platform.

Suggested-by: Jeremy Kerr <jk@codeconstruct.com.au>

v4:
 - removed i3c aliases
 - renamed i3c-global node name to generic: syscon
v3:
 - add i3c aliases
 - rebase on top of latest tree and solve conflicts
 - as agreed with Jeremy off-list, he said I can take authorship of this going forward
v2:
 - use inline bus representation, without the i3c: label
