thermal: int340x: Update OS policy capability handshake

Update the firmware with OS supported policies mask, so	that firmware can
relinquish its internal controls. Without this update several Tiger Lake
laptops gets performance limited with in few seconds of executing in
turbo region.

The existing way of enumerating firmware policies via IDSP method and
selecting policy by directly writing those policy UUIDS via _OSC method
is not supported in newer generation of hardware.

There is a new UUID "B23BA85D-C8B7-3542-88DE-8DE2FFCFD698" is defined for
updating policy capabilities. As part of ACPI _OSC method:

Arg0 - UUID: B23BA85D-C8B7-3542-88DE-8DE2FFCFD698
Arg1 - Rev ID: 1
Arg2 - Count: 2
Arg3 - Capability buffers: Array of Arg2 DWORDS

DWORD1: As defined in the ACPI 5.0 Specification
- Bit 0: Query Flag
- Bits 1-3: Always 0
- Bits 4-31: Reserved

DWORD2 and beyond:
- Bit0: set to 1 to indicate Intel(R) Dynamic Tuning is active, 0 to
indicate it is disabled and legacy thermal mechanism should
be enabled.
- Bit1: set to 1 to indicate Intel(R) Dynamic Tuning is controlling
active cooling, 0 to indicate bios shall enable legacy thermal
zone with active trip point.
- Bit2: set to 1 to indicate Intel(R) Dynamic Tuning is controlling
passive cooling, 0 to indicate bios shall enable legacy thermal
zone with passive trip point.
- Bit3: set to 1 to indicate Intel(R) Dynamic Tuning is handling
critical trip point, 0 to indicate bios shall enable legacy
thermal zone with critical trip point.
- Bits 4:31: Reserved

From sysfs interface, there is an existing interface to update policy
UUID using attribute "current_uuid". User space can write the same UUID
for ACTIVE, PASSIVE and CRITICAL policy. Driver converts these UUIDs to
DWORD2 Bit 1 to Bit 3. When any of the policy is activated by user
space it is assumed that dynamic tuning is active.

For example
$cd /sys/bus/platform/devices/INTC1040:00/uuids
To support active policy
$echo "3A95C389-E4B8-4629-A526-C52C88626BAE" > current_uuid
To support passive policy
$echo "42A441D6-AE6A-462b-A84B-4A8CE79027D3" > current_uuid
To support critical policy
$echo "97C68AE7-15FA-499c-B8C9-5DA81D606E0A" > current_uuid

To check all the supported policies
$cat current_uuid
3A95C389-E4B8-4629-A526-C52C88626BAE
42A441D6-AE6A-462b-A84B-4A8CE79027D3
97C68AE7-15FA-499c-B8C9-5DA81D606E0A

To match the bit format for DWORD2, rearranged enum int3400_thermal_uuid
and int3400_thermal_uuids[] by swapping current INT3400_THERMAL_ACTIVE
and INT3400_THERMAL_PASSIVE_1.

If the policies are enumerated via IDSP method then legacy method is
used, if not the new method is used to update policy support.
