Subject: tmio: add a platform flag to disable card write-protection detection
From: Guennadi Liakhovetski <g.liakhovetski@xxxxxx>
Write-protection status is not always available, e.g., micro-SD cards do
not have a write-protection switch at all. This patch adds a flag to let
platforms force tmio_mmc to consider the card writable.
