thermal/drivers/ti-soc-thermal: Remove unused declarations

The functions definition of ti_bandgap_read_thot(),
ti_bandgap_write_thot(), ti_bandgap_read_tcold() and
ti_bandgap_write_tcold() has been removed since commit 9bebf3485c6a
("thermal: ti-soc-thermal: remove dead code"), remain the declarations
untouched in the header files. So, clean up this unused declarations.
