ARM: keystone: introducing TI Keystone platform

Texas Instruments Keystone family of multicore devices now includes an
upcoming slew of Cortex A15 based devices.  This patch adds basic definitions
for a new Keystone sub-architecture in ARM.

Subsequent patches in this series will extend support to include SMP and take
advantage of the large physical memory addressing capabilities via LPAE.
