microblaze idle: Fix compile error

Commit def8203 ("microblaze idle: delete pm_idle") introduced the following
compile error:

	arch/microblaze/kernel/process.c: In function 'cpu_idle':
	arch/microblaze/kernel/process.c:100: error: 'idle' undeclared (first use in this function)
	arch/microblaze/kernel/process.c:100: error: (Each undeclared identifier is reported only once
	arch/microblaze/kernel/process.c:100: error: for each function it appears in.)
	arch/microblaze/kernel/process.c:106: error: implicit declaration of function 'idle'

This patch fixes it.
