Subject: [PATCH] Blackfin arch: explicit add a might sleep to gpio_free

According to the documentation gpio_free should only be called from task
context only.  To make this more explicit add a might sleep to all
implementations.

This patch changes the gpio_free implementations for the blackfin
architecture.
