CHROMIUM: rts_pstor: fix formatting, writing, copying failures with

specific SDSDB cards.

Patch from Realtek to correct init option for specific SD cards -
Realtek found those cards cannot be successfully written (read is OK)
because current mount option causes writes(maybe to update the access time) when read.

TEST=insert SDSDB/SDSC card, format and cannot copy files to the card.

BUG=chrome-os-partner:15774
