[PATCH v3 2/2] ARM: s3c24xx: Correct SD card write protect detection on Mini2440

[Cedric Roux]

The mini2440 computer uses "active high" to signal that the "write protect"
of the inserted MMC is set. The current code uses the opposite, leading to
a wrong detection of write protection. The solution is simply to use
".wprotect_invert = 1" in the description of the MMC.
