media: imx7.rst: Fix ReST syntax

Sphinx didn't like the code-blocks on this file:

	Documentation/media/v4l-drivers/imx7.rst:19: WARNING: Inline substitution_reference start-string without end-string.
	Documentation/media/v4l-drivers/imx7.rst:20: WARNING: Block quote ends without a blank line; unexpected unindent.
	Documentation/media/v4l-drivers/imx7.rst:27: WARNING: Inline substitution_reference start-string without end-string.
	Documentation/media/v4l-drivers/imx7.rst:79: WARNING: Error in "code-block" directive:

	                    -> "imx7-mipi-csis.0":0 [ENABLED]

Fix them, in order to match the expected syntax for code blocks.
