refactor(ti): add top level ti_sci transport layer
The TI SCI transport header will allow us to abstract all transport
related calls from the actual medium of transport which can vary
from device to device.
For eg. it is sec proxy for current TI K3 devices, but in future it
maybe mailbox like in the TI AM62L.
With this change, we no longer need to include anything from the IPC
folder, so drop it from plat_common.mk
