arm: omap-common: adds secure image name common to, OMAP and keystone

As K2 can directly boot u-boot, add u-boot_HS_MLO as the secure image while booting secure K2 devicesr, for all boot modes other than SPI flash.

---

Changes in v3: None
Changes in v2:
- Adds a new name for the signed output image in config_secure.mk to keep it in line with the image name used by non-secure keystone devices.
