Some boards may use more than 4 temperature sensors for DPTF thermal
control, so this patch adds support for one more temperature sensor.

In the initial DPTF refactor, the scope of the TCPU device was
incorrectly set as \_SB, instead of \_SB.PCI0. However, because of the
way that the acpi_inject_dsdt() callback currently works (it injects
contents before the dsdt.aml file), the Scope where the TCPU
device lives (\_SB.PCI0) doesn't exist yet. Therefore, to avoid playing
games with *when* things are defined in the DSDT, switch to defining all
of the DPTF devices in the SSDT.

DPTF has several options on how to control the fan (fine-grained speed
control, minimum speed change in percentage points, and whether or not
the DPTF device should notify the Fan if it detects low speed).
Individual TSRs can also set GTSH, which is the amount of hysteresis
inherent in the measurement, either from circuitry (if analog), or in
firmware (if digital).

This change adds support for emitting the PPCC table, which describes
the ranges available as knobs for DPTF to tune. It can support min/max
power, min/max time window for averaging, and the minimum adjustment size
(granularity or step size) of each power limit. The current implementation
only supports PL1 and PL2.

This change adds support for generating the _FPS table for the DPTF Fan
object. The table describes different levels of fan activity that may be
applied to the system in order to actively cool it. The information
includes fan speed at a (rough) percentage level, fan speed in RPM,
potential noise level in centibels, and power in mA.
