Partially revert f38e21fa6c ("Update PSoC 6 BSPs to verion 1.2") to
restore TF-M compatibility.
Make the CY8CKIT_064S2_4343W target TF-M compatible by addding flash and
region definitions from TF-M (at c4f37c18c4a0) and by updating the
CY8CKIT_064S2_4343W linker script to create a flash image compatible
with TF-M.
