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

[Bin Meng <bmeng.cn@gmail.com>]

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.
