[PATCH v2 1/8] spl: Kconfig: allow K3 devices to use falcon mode

[Anshul Dalal <anshuld@ti.com>]

Falcon mode was disabled for TI_SECURE_DEVICE at commit e95b9b4437bc
("ti_armv7_common: Disable Falcon Mode on HS devices") for older 32-bit
HS devices and can be enabled on K3 devices.

For secure boot, the kernel with x509 headers can be packaged in a fit
container (fitImage) signed with TIFS keys for authentication.

We also set the default SPL_PAYLOAD_ARGS_ADDR which holds the DTB to
match ATF's K3_HW_CONFIG_BASE.
