[PATCH 2/3] dt-bindings: i3c: ast2600: Add resets and reset-names

[Dylan Hung <dylan_hung@aspeedtech.com>]

Add two reset lines to the AST2600 I3C controller:
- core_rst: the reset line of the controller itself
- global_rst: the reset line of the I3C global register block. Since all
six I3C controllers in AST2600 share this global register block, the
driver needs to handle this carefully. Generally, this reset line should
only need to be de-asserted.
