ti_armv7_common: Disable Falcon Mode on HS devices

Browse source 
Authentication of images in Falcon Mode is not supported. Do not enable
SPL_OS_BOOT when TI_SECURE_DEVICE is enabled. This prevents attempting
to directly load kernel images which will fail, for security reasons,
on HS devices, the board is locked if a non-authenticatable image load
is attempted, so we disable attempting Falcon Mode.
