arm64: dts: apple: add opp-microwatt to t8103/t600x

This patch adds measured opp-microwatt values for the
Firestorm and Icestorm application cores found in Apple's
T8103 (M1), T6000 (M1 Pro), T6001 (M1 Max) and T6002 (M1 Ultra) SoCs.

Values were measured from the System Management Controller's
core cluster power meter. A version of freqbench modified
to read this power meter was used to orchestrate testing,
running 1,000,000 iterations of coremark on a single core
from each cluster at each operating point. The bulk of the
testing was done on a T6000.

Note that Apple calibrates voltage regulator settings for
each SoC as they come off the assembly line, introducing some
natural variance between machines. Testing across multiple
machines with identical SoCs reveals no measurable impact
on the accuracy of the EM subsystem's cost calculations.
