[PATCH v2 7/8] hw/sd: sd: Skip write protect groups check in CMD24/25 for high capacity cards |

From: Bin Meng <bin.meng@windriver.com>
High capacity cards don't support write protection hence we should
not preform the write protect groups check in CMD24/25 for them.

Changes in v2:
- new patch: sd: Skip write protect groups check in CMD24/25 for high capacity
