[U-Boot] [PATCH] hawkboard/omapl-138: Add support for generating ais image for hawkboard

[Sughosh Ganu]

Parameters used for configuring certain SoC peripherals are parsed
from the cfg file and appended as part of the ais image's header. The
u-boot-spl.ais generated is flashed separately to the nand, so do not
delete the file after generation of u-boot.ais.
