Latest changes: Report graphics controller and DRAM controller power and energy
consumption if supported. Add support for suspend/resume (turns out that was
necessary).

Output:

SandyBridge:

coretemp-isa-0000
Adapter: ISA adapter
Physical id 0:    +31.0°C  (high = +80.0°C, crit = +98.0°C)
Core 0:           +21.0°C  (high = +80.0°C, crit = +98.0°C)
Core 1:           +29.0°C  (high = +80.0°C, crit = +98.0°C)
Core 2:           +31.0°C  (high = +80.0°C, crit = +98.0°C)
Core 3:           +27.0°C  (high = +80.0°C, crit = +98.0°C)
Pkg power:         3.60 W  (max =  95.00 W, cap =  95.00 W)
Cores power:     407.00 mW
Graphics power:  251.00 mW
Pkg energy:       48.30 kJ
Cores energy:      7.02 kJ
Graphics energy:   3.34 kJ

IvyBridge:

coretemp-isa-0000
Adapter: ISA adapter
Physical id 0:    +29.0°C  (high = +85.0°C, crit = +105.0°C)
Core 0:           +27.0°C  (high = +85.0°C, crit = +105.0°C)
Core 1:           +28.0°C  (high = +85.0°C, crit = +105.0°C)
Core 2:           +26.0°C  (high = +85.0°C, crit = +105.0°C)
Core 3:           +28.0°C  (high = +85.0°C, crit = +105.0°C)
Pkg power:         4.04 W  (max =  77.00 W, cap = 1000.00 W)
Cores power:     818.00 mW  (cap =   1.20 kW)
Graphics power:    0.00 W  (cap =   1.20 kW)
Pkg energy:        3.93 kJ
Cores energy:    493.78 J
Graphics energy:  14.64 J

IvyBridge graphics power is quite low and zero if the console is in sleep mode.

turbostat reports the same values.
