dt-bindings: power: apple,pmgr-pwrstate: Add M3 compatibles

The blocks on Apple M3 and M3 Pro, Max and Ultra SoCs are compatible
with the existing driver so add their per-SoC compatibles. Add
"apple,t8122-pmgr-pwrstate" for the M3 and "apple,t6030-pmgr-pwrstate"
for M3 Pro, Max and Ultra as compatibles.
