The SDcard initialization procedure does a few more things than it did earlier:
* switch the bus width even for 1-bit bus width
* check that speed has been properly set (in resp[4] of SD_CMD_SWITCH_FUNC)
Update the SD simulator to handle those requests gracefully.

These functions can be much simpler by squashing lines for immediate
return.
For *_bind() callbacks, they will be a simple wrapper function of an
upper-level bind API.
For mmc_set_{boot_bus_width,part_conf}, they will be a wrapper of
mmc_switch().

Add an emulation of an SD card to sandbox, allowing MMC to be used in tests.
The emulation is very simple, supporting only card detection and reading
test data.

Add a test to confirm that we can probe this device. Since there is no
MMC stack support in sandbox at present, this is as far as the test goes.
