[PATCH 6.18.y] media: dt-bindings: nxp,imx8-isi: Drop fsl,blk-ctrl requirement for i.MX8ULP

[Sasha Levin <sashal@kernel.org>]

From: Guoniu Zhou <guoniu.zhou@oss.nxp.com>

[ Upstream commit fc312f830d8df6c082bd6f7250aa5c0ff063eea4 ]

The i.MX8ULP variant does not require the fsl,blk-ctrl property. Add
fsl,imx8ulp-isi to the exception list alongside fsl,imx91-isi.

Fixes: 288517a3c6c9 ("dt-bindings: media: nxp,imx8-isi: Add i.MX8ULP ISI compatible string")

[ added the missing fsl,blk-ctrl conditional using const instead of enum because this branch lacks i.MX91 support. ]
