mmc: rmobile: add a compiler barrier
Building w/ GCC v5.2, the SD card access is broken due to invalid data in the response command reconstructed at the end of sh_sdhci_get_response(). Add a memory barrier between the two main steps of this function to ensure the resp[] table content is consistent before bits reordering. This fix has been tested Ok on Porter board rev1.0 using v2016.03 release. Signed-off-by: Yannick Gicquel <yannick.gicquel@iot.bzh>
