Subject: [PATCH] arm64: dts: imx8mq: remove interconnect property from lcdif

The mxsfb driver handling imx8mq lcdif doesn't yet request the
interconnect bandwidth that's needed at runtime when the description is
present in the DT node.

So remove that description and bring it back when it's supported.

Fixes: ad1abc8a03fd ("arm64: dts: imx8mq: Add interconnect for lcdif")
