This makes the LEDs driver for ALIX2.C boards work with Coreboot by
looking up the port address in the MSR rather than hard-coding it.
The BIOS scan also needed some tweaks as the string in Coreboot differs
from the one in the legacy BIOS.
Successfully tested with both the legacy tinyBIOS as well as Coreboot
v3.

Add suspend/resume to the core class and remove all the now unneeded
code from various drivers. Originally the class code couldn't support
suspend/resume but since class_device can there is no reason for
each driver doing its own suspend/resume anymore.
Driver for PC Engines ALIX.2 and ALIX.3 LEDs.
