[ Upstream commit 09b964afca14d0594b2b2f265df3d987e2f43867 ]

The Orange Pi Win has a microSD card slot which is connected via all
four SD data lines. As the DT was not mentioning this fact, we got the
default single bit transfers, losing out on performance.
Also, as microSD does not have a write protect switch, we disable this
feature in the DT node.
