Marek Szyprowski 4b329d1a2f cpufreq: dt: always allocate zeroed cpumask 
[ Upstream commit d2399501c2 ]

Commit 0499a78369 ("ARM64: Dynamically allocate cpumasks and increase
supported CPUs to 512") changed the handling of cpumasks on ARM 64bit,
what resulted in the strange issues and warnings during cpufreq-dt
initialization on some big.LITTLE platforms.

This was caused by mixing OPPs between big and LITTLE cores, because
OPP-sharing information between big and LITTLE cores is computed on
cpumask, which in turn was not zeroed on allocation. Fix this by
switching to zalloc_cpumask_var() call.

Fixes: dc279ac6e5 ("cpufreq: dt: Refactor initialization to handle probe deferral properly")
