[PATCH RFC] blackfin: make timeout HZ independent

[Nicholas Mc Guire]

The timeout is in jiffies so the hard-coded numeric value becomes HZ
dependent, which is probably not the intent. To resolve this the 
timeout is converted with msecs_to_jiffies.

Due to tool-chain problems this patch was not even compile tested, further 
it is unclear if the interpretation of 5000 as 5000 milliseconds is even 
correct it is based on looking at other archs (e.g arch/arm64/kernel/smp.c,
arch/arm/kernel/smp.c...) which use msecs_to_jiffies(5000), but other
architectures use completely different timeouts.

Patch is against 3.19.0 (localversion-next is -next-20150210)
