[PATCH] power: vexpress: make dev_attr_active static

[Ben Dooks]

The dev_attr_active is not exported or defined to be used
outside the driver, so make it static to avoid the following
warning:

drivers/power/reset/vexpress-poweroff.c:77:1: warning: symbol 'dev_attr_active' was not declared. Should it be static?
