ARM: davinci: board-da850-evm: fix WP pin polarity for MMC/SD

Browse Source 
[ 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.
