[PATCH 1/2] arm64: dts: agilex5: set alias for i3c controllers for agilex5 variants

From: Adrian Ng Ho Yin <adrianhoyin.ng@altera.com>

Agilex5 SoCFPGA variants and derivities have 2 i3c controllers, a main
master and a secondary master. Setting the alias for both i3c controllers
to prevent bus id contention when both controllers are enabled which
results in driver probe failures.
