Cosmetic display change of Cx states via cx_supported sysctl entries.

Adjust power_profile script to handle the new world order as well.

Some vendors are opting out of a C2 state and only defining C1 & C3.  This
leads the acpi_cpu display to indicate that the machine supports C1 & C2
which is caused by the (mis)use of the index of the cx_state array as the
ACPI_STATE_CX value.

e.g. the code was pretending that cx_state[i] would
always convert to i by subtracting 1.

cx_state[2] == ACPI_STATE_C3
cx_state[1] == ACPI_STATE_C2
cx_state[0] == ACPI_STATE_C1

however, on certain machines this would lead to
cx_state[1] == ACPI_STATE_C3
cx_state[0] == ACPI_STATE_C1

This didn't break anything but led to a display of:
 * dev.cpu.0.cx_supported: C1/1 C2/96

Instead of
 * dev.cpu.0.cx_supported: C1/1 C3/96
