board: da8xxevm: Fix Environmental CRC error

When the spi_flash_probe_bus_cs() was previously called, it was
called using 0's for two values where CONFIG_ENV_SPI_MAX_HZ and
CONFIG_ENV_SPI_MODE are now used.  When changed this
caused the environment to fail the CRC check and the default
was used.  This patch defines both of these values back 0.

Fixes: 25a17652c9c2 ("fix: env: Fix the SPI flash device setup
for DM mode")
