qemu: android: Add support for multiple SD cards
Add commandline support for an additional SD card, and plumb support to
the MMC emulation layer. This patch also reworks the way the hw emulation
layer registers devices. Previously, the mmc virtual hardware was only
created if the sdcard image existed. Now, two virtual MMC controllers are
*always* created as on real hardware. When a request is made to one
of our controllers which has no image file bound to it, a new interrupt
status indicating a command timeout is sent to the guest driver, as
is standard with MMC controllers. This patch also sets the stage for
supporting hot-add / hot-remove.
