thermal: Constify static attribute_group structs

Commit Message

Rikard Falkeborn Nov. 28, 2020, 11:43 p.m. UTC

The only usage of these structs is to assign their address to the
thermal_zone_attribute_groups array, which consists of pointers to
const, so make them const to allow the compiler to put them in read-only
memory.
