thermal: intel: hfi: Increase the number of CPU capabilities per netlink event

Browse Source 
The number of updated CPU capabilities per netlink event is hard-coded to
16. On systems with more than 16 CPUs (a common case), it takes more than
one thermal netlink event to relay all the new capabilities after an HFI
interrupt. This adds unnecessary overhead to both the kernel and user space
entities.

Increase the number of CPU capabilities updated per event to 64. Any system
with 64 CPUs or less can now update all the capabilities in a single
thermal netlink event.
