Some platforms such Texas Instrument’s K3 familly of SoCs requires

Add a new option to select tee-raw.bin instead of tee.bin.

Raw binary suitable to copy into physical memory where OP-TEE
be can executed from.
OP-TEE since 3.21 suggests to use tee-raw.bin instead of (the
still identical) tee-pager_v2.bin.
Texas Instrument’s K3 family of SoCs embed tee-raw.bin in
U-Boot (using Binman tool) to support their boot flow.
