[PATCH v2 01/25] hw/sd/sdcard: Return ILLEGAL for CMD19/CMD23 prior SD spec v3.01

[Philippe Mathieu-Daudé]

From: Philippe Mathieu-Daudé <f4bug@amsat.org>

CMD19 (SEND_TUNING_BLOCK) and CMD23 (SET_BLOCK_COUNT) were
added in the Physical Layer Simplified Specification v3.01.
When earlier spec version is requested, we should return ILLEGAL.
