Pratik R. Sampat 5937a882dc cpufreq: powernv: Fix init_chip_info initialization in numa=off 
commit f34ee9cb2c upstream.

In the numa=off kernel command-line configuration init_chip_info() loops
around the number of chips and attempts to copy the cpumask of that node
which is NULL for all iterations after the first chip.

Hence, store the cpu mask for each chip instead of derving cpumask from
node while populating the "chips" struct array and copy that to the
chips[i].mask

Fixes: 053819e0bf ("cpufreq: powernv: Handle throttling due to Pmax capping at chip level")
