boot/uboot: add support for embedded TEE in raw binary format

Browse Source 
Some platforms such Texas Instrument’s K3 familly of SoCs requires
TEE in raw binary format to support their boot flow [1].

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.
