Add PROP method under \_SB.DPTF.TPWR scope which will return static
worst case rest of platform power in miliWatts.
This value is static, which has to configured from devicetree of
overridetree for each platform
BUG=b:205928013
TEST=Build, boot brya0 and dump SSDT to check PROP method
Scope (\_SB)
{
Device (DPTF)
{
Device (TPWR)
{
Method (PROP, 0, Serialized)
{
Return (XXXX)
}
}
}
}
