[PATCH] cpufreq: brcmstb-avs-cpufreq: sort frequencies in ascending order

[Markus Mayer]

From: Markus Mayer <mma...@broadcom.com>

Most CPUfreq drivers (at least on ARM) seem to be sorting the available
frequencies from lowest to highest. To match this behaviour, we reverse
the sorting order in brcmstb-avs-cpufreq, so it is now also lowest to
highest.
