Add AMD Ryzen AI MAX+ 395 model to database

Adding the AMD Ryzen AI MAX+ 395.

The APU's max TDP is technically 120w on devices like the Apex and Super X if you have appropriate cooing (Frost Bay), but not all devices support that.

We also need to take the following factors into account (at least for the Onexplayer Apex):

• The maximum TDP while running on battery power is 55W
• The maximum TDP while charging via Type-C is 55W
• The maximum TDP while charging via a standard charger is 80W (without a cooling dock)

I’m not 100% sure, but failing to comply with these conditions may potentially damage the device.

Currently we don't have a way to detect if a device is attached to a fast charger or external cooling. To ensure safe operation until we can do that I'd prefer to limit this to the safe DC with native cooling max TDP for now.

TBS, this chip has a much higher TDP in some desktop like applications we don't want to throttle. This value should instead be set to the silicon max TDP per AMD, then device specific overrides should populate from the vendor database to keep the known handhelds under safe levels.

dtibragimov@hercules:/var/home/dtibragimov$ lscpu | grep 'Model name'
Model name:                              AMD RYZEN AI MAX+ 395 w/ Radeon 8060S

hence: model_name = "AMD RYZEN AI MAX+ 395 w/ Radeon 8060S"

in order to not break the devices for usual users: max_tdp should be equal 55w or 80w, 90 could overheat the device

as soon as the TDP becomes avialable in SteamOS QAM, it would be possible to change TDP manually above, say, 55w?

dtibragimov@hercules:/var/home/dtibragimov$ udevadm info -a /sys/class/dmi/id

Udevadm info starts with the device specified by the devpath and then
walks up the chain of parent devices. It prints for every device
found, all possible attributes in the udev rules key format.
A rule to match, can be composed by the attributes of the device
and the attributes from one single parent device.
