This patch makes some minor changes to how the sd card is described in the device tree for the ASUS Tinker Board (S). In particular on the Tinker Board S, when booted from the eMMC, and with no card in the sd slot, and the log has endless messages about not being able to detect the card. Several methods to remove this error have been tried, the only one that works is the broken-cd and so that is what is applied here. Alas the ASUS schematic is not clear enough to indicate if the card detect is wired up to the cpu, the schematic does not show internal wiring on the Tinker Board! Now this error didn't show up on the Tinker Board, as that machine only boots where there is a sd card installed. However as the TB and TBS are so similar it is expected that the Tinker Board also doesn't have a functioning card detect. Hence the change here is made to the dtsi file, so it applies to both TB and TBS. The disable-wp is also removed, it doesnt seem needed on the micro sdcard slots, and without thisn the card can still be written to. Hence this flag is also removed.
