5Description:	RW. Card reactive sustained  (PL1) power limit in microwatts.
6
7		The power controller will throttle the operating frequency
8		if the power averaged over a window (typically seconds)
9		exceeds this limit. A read value of 0 means that the PL1
10		power limit is disabled, writing 0 disables the
11		limit. Writing values > 0 and <= TDP will enable the power limit.
12
13		Only supported for particular Intel Xe graphics platforms.
