arm: mvebu: Espressobin: Set the maximum slave SPI speed to 40MHz

Browse Source 
While the SPI controller speed is defined by DTS, the maximum
slave speed (connected devices) is limited by the pre-defined
configuration value CONFIG_SF_DEFAULT_SPEED to 1MHz
This patch increases this maximum SPI slave device speed to 40MHz
