[PATCH v4 9/9] hw/sd: ssi-sd: Handle the rest commands with R1b response type

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

From: Bin Meng <bin.meng@windriver.com>

Besides CMD12, the following command's reponse type is R1b:

- SET_WRITE_PROT (CMD28)
- CLR_WRITE_PROT (CMD29)
- ERASE (CMD38)

Reuse the same s->stopping to indicate a R1b reponse is needed.

Changes in v4:
- new patch: handle the rest commands with R1b response type
