From: Faiz Abbas <faiz_abbas@ti.com>

commit 4d627c88546a697b07565dbb70d2f9f46a5ee76f upstream.

The MMC/SD controllers on am65x and j721e don't in fact detect the write
protect line as inverted. No issues were detected because of this
because the sdwp line is not connected on any of the evms. Fix this by
removing the flag.
