ti: omap-common: Add commands for generating secure SPL images

Browse Source 
Adds a centralized config_secure.mk in omap-common for
OMAP-style TI secure devices to use for boot image generation

Depending on the boot media, different images are needed for
secure devices. These commands generates u-boot*_HS_* files that
need to be used to boot secure devices.

Please refer to README.ti-secure for more information.
