Subject: PM: Do not require dev spew to get PM_DEBUG
From: Ben Collins <bcollins@xxxxxxxxxx>
In order to enable things like PM_TRACE, you're required to enable
PM_DEBUG, which sends a large spew of messages on boot, and often times can
overflow dmesg buffer.
Create new PM_VERBOSE and shift that to be the option that enables
drivers/base/power's messages.
