hwmon: (coretemp) Enlarge per package core count limit



[ Upstream commit 34cf8c657cf0365791cdc658ddbca9cc907726ce ]

Currently, coretemp driver supports only 128 cores per package.
This loses some core temperature information on systems that have more
than 128 cores per package.
 [   58.685033] coretemp coretemp.0: Adding Core 128 failed
 [   58.692009] coretemp coretemp.0: Adding Core 129 failed
 ...

Enlarge the limitation to 512 because there are platforms with more than
256 cores per package.
