arm: mvebu: turris_omnia: Remove hardcoded spi-nor device tree path
Linux kernel DTS files renamed spi-nor@0 node to flash@0 which effectively
broke U-Boot to boot new Linux kernel versions correctly.
So remove hardcoded spi-nor device tree path from Turris Omnia board code
and replace it by searching for mtd node by compatible string.
