mmc: sdhci: Allow for finishing multiple requests
In order to support commands during data transfer, there will have to be up to two active requests (mrqs) at a time, instead of just one. That means recording which request is finished. Doing that obsoletes host->mrq which is therefore removed. Signed-off-by: Adrian Hunter <adrian.hunter@intel.com> Signed-off-by: Ulf Hansson <ulf.hansson@linaro.org>
