ti: AM43xx: config.mk: Add support for generating secure boot images
Modifies the config.mk to build secure images when building the SPL for secure devices. Depending on the boot media, different images are needed for secure devices. The build generates u-boot*_HS_* files as appropriate for the different boot modes. The same u-boot binary file is processed slightly differently to produce a different boot image, depending on whether the user wants to boot off SPI, QSPI or other boot media. Refer to README.ti-secure for more information.
