[PATCH 1/3] ti-soc-thermal: Use devm_kcalloc() in ti_bandgap_build()

A multiplication for the size determination of a memory allocation
indicated that an array data structure should be processed.
Thus use the corresponding function "devm_kcalloc".

This issue was detected by using the Coccinelle software.
