cpufreq: brcmstb-avs-cpufreq: extend sysfs entry brcm_avs_pmap
We extend the brcm_avs_pmap sysfs entry (which issues the GET_PMAP
command to AVS) to include all fields from struct pmap. This means
adding mode (AVS, DVS, DVFS) and state (the P-state) to the output.

ucture in CPU prepare and when it turns out to already exist in
starting throw it away later in the CPU online callback. But that's a
horrible hack and not required at all because RAPL becomes functional for
perf only in the CPU online callback. That's correct because user space is
not yet informed about the CPU being onlined, so nothing caan rely on RAPL
being available on that particular CPU.
Move the allocation to the CPU online callback and simplify the hotplug
handling. At this point the package mapping is established and correct.
This also adds a missing check for available package data in the
event_init() function.
