Subject: [PATCH v7 2/4] cpufreq: qcom-nvmem: also accept operating-points-v2-krait-cpu

From: Dmitry Baryshkov <dmitry.baryshkov@...aro.org>

the qcom-cpufreq-nvmem driver attempts to support both Qualcomm Kryo
(newer 64-bit ARMv8 cores) and Krait (older 32-bit ARMv7 cores). It
makes no sense to use 'operating-points-v2-kryo-cpu' compatibility node
for the Krait cores. Add support for 'operating-points-v2-krait-cpu'
compatibility string.
