Cygnus: add TrustZone functions and set everything non-secure in bootblock
To allow an OS to run in non-secure mode:
- Set all peripherals and system components non-secure except SOTP and TZPC.
- Set all memory non-secure (ROM, SRAM, DDR, flash).
- Enable A9 access to entire M0 address space except M0 ROM.
