hw/sd/sdcard: Restrict Class 6 commands to SCSD cards
Only SCSD cards support Class 6 (Block Oriented Write Protection)
commands.
"SD Specifications Part 1 Physical Layer Simplified Spec. v3.01"
4.3.14 Command Functional Difference in Card Capacity Types
* Write Protected Group
SDHC and SDXC do not support write-protected groups. Issuing
CMD28, CMD29 and CMD30 generates the ILLEGAL_COMMAND error.
