refactor(ti): move out k3/common to ti/common

This will allow us to support more platforms that share commonalities
like the k3_gicv3, console, helpers, etc.
With this new common folder location, we can move the previously
created ti_bl31_setup file into the new location so it can be shared
across multiple TI SoCs when need comes.
With this, also update all copyright dates.
