[PATCH 1/2] hwmon: (coretemp) replace hardcoded core count with dynamic value

[bakshansky.lists@gmail.com]

From: Roman Bakshansky <bakshansky.lists@gmail.com>

The hardcoded maximum of 512 cores per package was first defined by commit
34cf8c657cf0 ("hwmon: (coretemp) Enlarge per package core count limit")
and later kept as a fallback with a TODO in commit 1a793caf6f69 ("hwmon:
(coretemp) Use dynamic allocated memory for core temp_data") because the
actual per-package core count was not reliably available at the time.

Now that topology_num_cores_per_package() is stable and suitable for use,
it's time to complete the TODO and allocate only the needed amount of
memory for core_data.
