psoc64: Add TF-M compatibility

The CY8CKIT_064B0S2_4343W target was added as a replacement for the
prototype CY8CKIT_064S2_4343W target, but it is missing modifications
added to CY8CKIT_064S2_4343W to enable it to work with TF-M.

Make the CY8CKIT_064B0S2_4343W target TF-M compatible by addding flash
and region definitions from TF-M and by updating the
CY8CKIT_064B0S2_4343W linker script to create a flash image compatible
with TF-M.

+;* Linker file for the ARMCC.
+;*
+;* The main purpose of the linker script is to describe how the sections in the
+;* input files should be mapped into the output file, and to control the memory
+;* layout of the output file.
+;*
+;* \note The entry point location is fixed and starts at 0x10000000. The valid
+;* application image should be placed there.
+;*
+;* \note The linker files included with the PDL template projects must be
+;* generic and handle all common use cases. Your project may not use every
+;* section defined in the linker files. In that case you may see the warnings
+;* during the build process: L6314W (no section matches pattern) and/or L6329W
+;* (pattern only matches removed unused sections). In your project, you can
+;* suppress the warning by passing the "--diag_suppress=L6314W,L6329W" option to
+;* the linker, simply comment out or remove the relevant code in the linker
+;* file.
