hw/sd/omap_mmc: Don't use sd_cmd_type_t

In commit 1ab08790bb75e4 we did some refactoring of the SD card
implementation, which included a rearrangement of the sd_cmd_type_t
enum values. Unfortunately we didn't notice that this enum is not
used solely inside the SD card model itself, but is also used by the
OMAP MMC controller device. In the OMAP MMC controller, it is used
to implement the handling of the Type field of the MMC_CMD register,
so changing the enum values so that they no longer lined up with the
bit definitions for that register field broke the controller model.
The effect is that Linux fails to boot from an SD card on the "sx1"
machine.

Give omap-mmc its own enum which we can document as needing to match
the encoding used in this device's register, so it isn't sharing
sd_cmd_type_t with the SD card model any more. We can then move
sd_cmd_type_t's definition out of sd.h and into sd.c, which is the
only place that uses it.

hw/sd/sdcard: Basis for eMMC support

Since eMMC are soldered on boards, it is not user-creatable.

RCA register is initialized to 0x0001, per spec v4.3,
chapter 8.5 "RCA register":

The default value of the RCA register is 0x0001.
The value 0x0000 is reserved to set all cards into
the Stand-by State with CMD7.

The CSD register is very similar to SD one, except
the version announced is v4.3.

eMMC CID register is slightly different from SD:
- One extra PNM (5 -> 6)
- MDT is only 1 byte (2 -> 1).

dd if=u-boot-spl.bin of=mmc-bootarea.img conv=notrunc

cat mmc-bootarea.img obmc-phosphor-image.wic > mmc.img
truncate --size 16GB mmc.img
truncate --size 128MB mmc-bootarea.img

For now this still requires a mtd image to load the SPL:

qemu-system-arm -M tacoma-bmc -nographic \
-global driver=sd-card,property=emmc,value=true \
-drive file=mmc.img,if=sd,index=2 \
