Peter Maydell 50b52b18cd hw/arm/mps2: Update old infocenter.arm.com URLs 
Update old infocenter.arm.com URLs to the equivalent developer.arm.com
ones (the old URLs should redirect, but we might as well avoid the
redirection notice, and the new URLs are pleasantly shorter).

This commit covers the links to the MPS2 board TRM, the various
Application Notes, the IoTKit and SSE-200 documents.

/* The MPS2 and MPS2+ dev boards are FPGA based (the 2+ has a bigger
* FPGA but is otherwise the same as the 2). Since the CPU itself
* and most of the devices are in the FPGA, the details of the board
* as seen by the guest depend significantly on the FPGA image.
* This source file covers the following FPGA images, for TrustZone cores:
* "mps2-an505" -- Cortex-M33 as documented in ARM Application Note AN505
* "mps2-an521" -- Dual Cortex-M33 as documented in Application Note AN521
* "mps2-an524" -- Dual Cortex-M33 as documented in Application Note AN524
*
* Links to the TRM for the board itself and to the various Application
* Notes which document the FPGA images can be found here:
* https://developer.arm.com/products/system-design/development-boards/fpga-prototyping-boards/mps2
*
* Board TRM:
* https://developer.arm.com/documentation/100112/latest/
* Application Note AN505:
* https://developer.arm.com/documentation/dai0505/latest/
* Application Note AN521:
* https://developer.arm.com/documentation/dai0521/latest/
* Application Note AN524:
* https://developer.arm.com/documentation/dai0524/latest/
*
* The AN505 defers to the Cortex-M33 processor ARMv8M IoT Kit FVP User Guide
* (ARM ECM0601256) for the details of some of the device layout:
* https://developer.arm.com/documentation/ecm0601256/latest
* Similarly, the AN521 and AN524 use the SSE-200, and the SSE-200 TRM defines
* most of the device layout:
