Seunghui Lee 2e911496d8 mmc: core: Set read only for SD cards with permanent write protect bit ...

commit 917a5336f2 upstream.

Some of SD cards sets permanent write protection bit in their CSD register,
due to lifespan or internal problem. To avoid unnecessary I/O write
operations, let's parse the bits in the CSD during initialization and mark
the card as read only for this case.
