[Daniele Ceraolo Spurio]

From: Alexander Usyskin <alexander.usyskin at intel.com>

Add Lunar (Point) Lake M device id.

xe-for-ci note: this patch is being reviewed for merge via the char-misc
tree [1]. We need this for LNL GSC proxy, so we're pulling it early to
the xe-for-ci tree to unblock our LNL execution.
