ARM: 7029/1: Make cpu_architecture into a global variable

Browse Source 
The CPU architecture really should not be changing at runtime, so
make it a global variable instead of a function.

The cpu_architecture() function declared in <asm/system.h> remains
the correct way to read this variable from C code.
