Subject: [PATCH] tools/power/x86/intel-speed-select: Support more than 8 sockets.

MAX_PACKAGE_COUNT limits the intel-speed-select to systems with 8 sockets or fewer.
On a system with more than 8 sockets intel-speed-select silently ignores everything
beyond the 8th socket, rendering the tool useless for those systems.

Increase MAX_PACKAGE_COUNT to support systems with up to 32 sockets.
