hwmon: tmp512: drop of_match_ptr for ID table

[ Upstream commit 00d85e81 ]

The driver will match mostly by DT table (even thought there is regular
ID table) so there is little benefit in of_match_ptr (this also allows
ACPI matching via PRP0001, even though it might not be relevant here).
This also fixes !CONFIG_OF error:

  drivers/hwmon/tmp513.c:610:34: error: ‘tmp51x_of_match’ defined but not used [-Werror=unused-const-variable=]

Fixes: 59dfa75e
