[U-Boot] [PATCH] mmc: Remove incorrect cmd->flags usage

[Marek Vasut]

Dear Andy Fleming,

> There were a couple of drivers that were actually using the flags
> field of the cmd structure, despite the fact that no one ever
> *set* that field. When we removed the field, those drivers failed
> to compile. Replaced the references with the correct usage of
> resp_type.

I'll run duts tests on this on M28, stay tuned.
