Changes to move hawkboard to the new spl infrastructure

This patch moves hawkboard to the new spl infrastructure from the
older nand_spl one.

Removed the hawkboard_nand_config build option -- The spl code now
gets compiled with hawkboard_config, after building the main u-boot
image, using the CONFIG_SPL_TEXT_BASE. Modified the README.hawkboard
to reflect the same.
