Subject: [PATCH 1/2] cpufreq: brcmstb-avs-cpufreq: extend sysfs entry brcm_avs_pmap

From: Markus Mayer <mmayer@...adcom.com>

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.
