mb/google/brya/var/redrix{4es}: Set tcc_offset value to 3 

The redrix thermal team has determined that the TCC circuit trip
temperature should be set to 97C, therefore, because the offset
is subtracted from 100C, set the `tcc_offset` register in the
devicetree to 3.

BUG=b:200134784
TEST=build and verified by thermal team
