apple: derive CPU speed from mpidr_el1
According to https://github.com/AsahiLinux/docs/wiki/HW%3AARM-System-Registers,
MPIDR_EL1 Aff2 determines whether a core is an efficiency or performance
core. Replace the compat data table with code that uses the aff2 value
for fake DMIPS/MHz value, to hopefully maintain compatibility with future
cores.
