No you can't do that, because BR2_PACKAGE_FREESCALE_IMX_PLATFORM_IMX6Q
is part of a choice, and you can not select a choice entry.

So a 'depends on' it must be in this case.

Not sure what to do about the comment, though. We currently have no such
case documented in the manual; only comments about toolchain deps are
described...

I'm not against adding comments about dependencies on other packages,
but I think we should keep them to a minimal level, like dependencies on
biggish stuff (like X.org), or non-obvious stuff.
