[meta-ti][master/kirkstone][PATCH v2 02/15] trusted-firmware-a: Use new ti-secdev class to sign the images

[Andrew Davis <afd@ti.com>]

Use the new ti-k3-secdev package to pull in the signing tools if they are
not provided by the environment. This allows us to use these tools
unconditionally. Remove the checks for the script and do the signing
for all K3 machines. The signature is automatically stripped from
the binaries on non-HS devices at boot time as needed so this change
is harmless for GP devices.
