[PATCH V2 1/2] hwmon: uniform the init style of pkgtemp
[PATCH V2 2/2] hwmon: cleanup some hotplug related macro definition

These 2 patches don't supply new functions, just unify the codes to avoid
potential issues and some cleanup work.

V2: fix some compile errors.

[lm-sensors] [PATCH V2 1/2] hwmon: uniform the init style of pkgtemp

[Chen Gong]

pkgtemp is derived from coretemp, so some reasonable
logics should be applied onto pkgtemp, too. Such as
the init logic here.

Please rebase this patch to

Some of the changes are already applied through other patches.
