ARM: iWMMXt: always enable iWMMXt support with PJ4 CPUs 

Jason Cooper reports these build errors:
arch/arm/kernel/built-in.o: In function `iwmmxt_do':
/.../arch/arm/kernel/pj4-cp0.c:36: undefined reference to `iwmmxt_task_release'
/.../arch/arm/kernel/pj4-cp0.c:40: undefined reference to `iwmmxt_task_switch'
make: *** [vmlinux] Error 1

This is caused because the PJ4 code explicitly references the iWMMXt
code, but doesn't require it to be built.  Fix this by ensuring that
iWMMXt is always enabled with PJ4.

Enable support for iWMMXt context switching at run time if
running on a CPU that supports it.
