The core types of the M4 SoC no longer carry individual codenames.
Apple's device trees re-use the 'everest' and 'sawtooth' codenames from
the M3 generation for all later cores.

Instead, we use a combination of the SoC's codename ('Donan') and the
type of core ('e' and 'p' for the efficiency and performance cores
respectively) as compatible for these cores.
