[U-Boot] [RFC 6/9] arm: omap5: add FIT image post process function

[Andreas Dannenberg]

From: Daniel Allred <d-allred at ti.com>

Adds a board specific FIT image post processing function for when
CONFIG_SECURE_BOOT is defined.  Also update the omap common config
header to enable CONFIG_SECURE_BOOT always for secure TI devices
(CONFIG_TI_SECURE_DEVICE is defined).
