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.
