hw/sd/sdhci: Add dummy Samsung SDHCI controller

Browse source 
The Linux kernel access few S3C-specific registers [1] to set some
clock. We don't care about this part for device emulation [2]. Add
a dummy device to properly ignore these accesses, so we can focus
on the important registers missing.
