The MIB INFO command is fetching MIB_BUSY_TIME, MIB_TX_TIME, MIB_RX_TIME and
MIB_OBSS_AIRTIME from the radio and filling out cc_busy, cc_tx, cc_bss_rx
and cc_rx respectively.
busy should be >= tx + rx >= tx + bss_rx but we don’t always quite see this.
Sometimes tx + rx is a bit higher than busy due to inaccurate accounting,
so this patch recalculates numbers to make them more reasonable.

Add the missing CPU topology/capacity information and the cpufreq nodes,
so we can have CPU frequency scaling and the scheduler has the
information it needs to make the correct decisions.
Boost states are commented out, as they are not yet available (that
requires CPU deep sleep support, to be eventually done via PSCI).
The driver supports them fine; the hardware will just refuse to ever
go into them at this time, so don't expose them to users until that's
done.
