[PATCH v1] i3c: master: ast2600: Fix missing of_node for virtual I2C adapter

[Peter Yin]

The ASPEED AST2600 I3C master driver creates a virtual I2C adapter to
provide backward compatibility with I2C devices. However, the current
implementation does not associate this virtual adapter with any
Device Tree node.

This patch propagates the of_node from the I3C master platform device
to the virtual I2C adapter's device structure. This ensures that
standard I2C aliases are correctly resolved and bus numbering remains
consistent across reboots.
