4.14-stable review patch. If anyone has any objections, please let me know.

[ Upstream commit 1b6fe9798af8cb7d80fad5dd30ee1bcd1e0f51eb ]
When booting from MMC/SD in rw mode on DA850 EVM, the system crashes because the write protect pin should be active high and not active low. This patch fixes the polarity of the WP pin.
