refactor(tc): use internal trusted storage

Browse source 
Trusted Services had removed secure storage and added two new
trusted services - Protected Storage and Internal Trusted Storage.
Hence we are removing secure storage and adding support for the
internal trusted storage.

And enable external SP images in BL2 config for TC, so that
we do not have to modify this file whenever the list of SPs
changes. It is already implemented for fvp in the below commit.
