From: Nagabhushana Netagunte <nagabhushana.netagunte@ti.com>

Enable SPI flash boot mode in configuration file as default.
With the introduction of 456MHz part, SPI operating frequency
will increase and at this frequency SPI does not work correctly.
Hence reduce the default SPI speed to 30MHz from 50MHz.
