[Qemu-devel] [PULL 17/32] sdcard: Don't always set the high capacity bit |

From: Philippe Mathieu-Daudé <address@hidden>
Don't set the high capacity bit by default as it will be set if required
in the sd_set_csd() function.
[based on a patch from Alistair Francis <address@hidden>
and Peter Ogden <address@hidden> from qemu/xilinx tag xilinx-v2015.4]
