arm: mvebu: clearfog: Fix SPI-NOR flash access
The production variant of the SPI flash used by the clearfog
devices are based on winbond chips. Additionally enable
SPI_FLASH_BAR since some variants will have 16MB of flash
that requires this to be enabled.
Remove the default speed and mode; these values are taken from the
device tree when CONFIG_DM_SPI_FLASH is enabled.
Add default bus, so that 'sf' detects the SPI flash by default.
