ucm-imx95: fix firmware parameter collision and update imx-mkimage

Fixed parameter name collision in ucm-imx95-firmware.nix where the
'silicon' parameter conflicted with the nixpkgs silicon package, causing
the wrong AHAB container to be selected. Renamed to 'siliconRev'.

Updated imx-mkimage from lf-6.6.36 to lf-6.6.52-2.2.1 to match the
firmware version expectations (v202409 instead of v202311).
