arm64: dts: apple: Add devicetreee for t8112-j415

Browse Source 
The 15-inch M2 MacBook Air was released a year after the 13-inch one
thus missed in initial submission of devicetrees for M2 based devices.
It is currently a copy of t8112-j413 with edited identifiers but will
eventually differ in a meaningful way. It has for example a different
speaker configuration than the 13-inch model.
