Drop VRM reporting and selection support from libsensors. Since kernel

2.6.9, the right VID conversion formula is selected automatically
depending on the CPU model, so the user shouldn't have to care.

 AMD Opteron 24x processors.
 Note that versions 8.1 - 8.4 are compatible.
 
-lm_sensors versions through 2.6.3 support only the VRM 8.2 standard.
-
-Starting in lm_sensors 2.6.4 the VRM version is configurable.
-To configure the sensor chip for the correct voltage range,
-you must set the "vrm" correctly either via /proc, /sys,  or sensors.conf.
-
-To be compatible with previous lm_sensors versions, the vrm defaults
-to version 8.2. Generally, for recent motherboards, this will not
-be correct. Try 9.0 first.
-
-To change the vrm version to 9.0, for example, do the following
-after the chip module (in this example, w83781d) is loaded:
-
-	(kernel 2.4)
-	    echo 9.0 > /proc/sys/dev/sensors/w83781d-isa-0290/vrm
-	(kernel 2.6)
-	    echo 90 > /sys/bus/i2c/devices/0-0290/vrm
-
-Alternatively, add a line in /etc/sensors.conf in the w83781d section
-(you should put this line BEFORE any line that uses vid in a calculation):
-
-	set vrm 9.0
-
-and then, after the chip module is loaded, do:
-
-	sensors -s
-
-After this, reading the vid either by
-
-	(kernel 2.4)
-	    cat /proc/sys/dev/sensors/w83781d-isa-0290/vid
-	(kernel 2.6 - divide the output by 1000)
-	    cat /sys/bus/i2c/devices/0-0290/in0_ref
-
-or by
-
-	sensors
-
-should show the new vid value.
-
-
-The following values are legal vrm values. Other values will be
-allowed but will result in using the 8.2 standard.
-
-	2.4, 8.1-8.5, 9.0, 9.1, 10.0
-
+Since Linux 2.6.9, the correct VRM version is selected automatically
+based on the CPU brand and model. Thus you shouldn't have to care about
+it. If you are using a brand new CPU and even the latest kernel complains
+("Unknown VRM version of your CPU"), this means that the kernel must be
+taught about this new CPU model. Please report to us in this case.
 
 Remember, the VID pins on the sensor chips are inputs only.
-That means they can't be changed and there shouldn't be
-any problems if you experiment with the vrm values until you
-get it right. You cannot manipulate the actual processor core
-voltage through lm_sensors drivers.
-
-Not all sensor chips have VID inputs.
-For those that do, the VRM support status is listed below.
-
-The following chip drivers support all the VRM versions via
-/etc/sensors.conf and the vrm entry in /proc or /sys:
-
-	adm1025, adm1026, asb100, lm85, lm87,
-	vt1211, vt8231, w83627hf, w83781d
-
-
-The following chip drivers support only VRM 8.2 and cannot be changed:
-
-	adm1024, it87, mtp008
-	adm9240, gl520sm, lm78, maxilife
-
-If you have a board with one of these chips which needs advanced
-VRM support please email us.
+You cannot use them to manipulate the actual processor core voltage.
