ARM: Fix Versatile/Realview/VExpress MMC card detection sense
The MMC card detection sense has become really confused with negations at various levels, leading to some platforms not detecting inserted cards. Fix this by converting everything to positive logic throughout, thereby getting rid of these negations. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
