hw/arm/exynos4210: Use the Samsung s3c SDHCI controller
The Exynos SoC has specific SDHCI registers. Use the s3c SDHCI
model which handle these specific registers.
This silents the following "SDHC ... not implemented" warnings so
we can focus on the important registers missing:
$ qemu-system-arm ... -d unimp \
-append "... root=/dev/mmcblk0 rootfstype=ext4 rw rootwait" \
-drive file=linux-build-test/rootfs/arm/rootfs-armv5.ext2,if=sd,format=raw
[...]
