Seunghui Lee 917a5336f2 mmc: core: Set read only for SD cards with permanent write protect bit 
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.
