This PR adds a reference implementation on how to use Trustzone in XIP mode. A NonSecure application is given access to all peripherals, with exception of the OTP peripheral and the memory range belonging to the Secure mini bootloader. The mini bootloader has a veneer giving access to some trivial function.
Note this PR also makes a small change to the DMA peripheral to enable the creation of raw transfers, in order to showcase that the DMA master can also be configured to be NonSecure.
