x86: cougarcanyon2: Update dts for SPI lock down
It turns out that like Braswell, Intel FSP for IvyBridge requires SPI controller settings to be locked down, as the U-Boot ICH SPI driver fails with the following message on Cougar Canyon 2 board: "ICH SPI: Opcode 9f not found" Update the SPI node property to indicate this fact.
