Subject: [PATCH 1321/1350] dtoverlays: Fix up imx500 overlays to have unique
 clock nodes

The overlay was creating DT nodes /clocks/clk-aicam and
/clocks/clk-aicam-gated for both cam0 and cam1, which resulted
in one failing.

The clock infrastructure creates the clock name from the node name
without any @N reg extension, so we can't just use that. The nodes
therefore have to be renamed.
