[PATCH 11/13] ARM: versatile: remove mps2 support

[PATCH 11/13] ARM: versatile: remove mps2 support

[Arnd Bergmann]

From: Arnd Bergmann <arnd@arndb.de>

The Arm mps2 platform is the reference implementation for Arm
microcontrollers and is useful for testing but not expected to be used
as a production device.

With all the Cortex-M based products gone, there is no longer a need
for a reference platform either, so remove it as well.

Yes, I have a patch for that in
