board: iot2050: update build documentation for OP-TEE

Set ta-target explicitly to correspond with OP-TEE recipe in

aarch64-linux-gnu-gcc: error: unrecognized command-line option ‘-mno-unaligned-access’
aarch64-linux-gnu-gcc: error: unrecognized command-line option ‘-mfloat-abi=hard’
make: *** [mk/compile.mk:159: out/arm-plat-k3/ta_arm32-lib/libdl/dlfcn.o] Error 1
