[ARM] 3363/1: [cleanup] process.c - fix warnings

Patch from Ben Dooks

Fix the following warnings from sparse:

arch/arm/kernel/process.c:86:6: warning: symbol 'default_idle' was not declared. Should it be static?
arch/arm/kernel/process.c:378:5: warning: symbol 'dump_fpu' was not declared. Should it be static?

Include <linux/elfcore.h> for dump_fpu() decleration, and
make default_idle() static as it is not used outside the file.
