drm/radeon/kms/pm: add mid profile
 
This adds an additional profile, mid, to the pm profile
code which takes the place of the old low profile.  The default
behavior remains the same, e.g., auto profile now selects between
mid and high profiles based on power source, however, you can now
manually force the low profile which was previously only available
as a dpms off state.  Enabling the low profile when the displays
are on has been known to cause display corruption in some cases.

# extract-ikconfig - Extract the .config file from a kernel image

# This will only work when the kernel was compiled with CONFIG_IKCONFIG.
#
# The obscure use of the "tr" filter is to work around older versions of
# "grep" that report the byte offset of the line instead of the pattern.
