Some function prototypes and body for Thermal Assist Units were not in sync. Update the function definition to match the existing function declaration found in `setup-common.c`, changing an `int` return type to a `u32` return type. Move the prototypes to a header file. Fix the following warnings, treated as error with W=1: arch/powerpc/kernel/tau_6xx.c:257:5: error: no previous prototype for ‘cpu_temp_both’ [-Werror=missing-prototypes] arch/powerpc/kernel/tau_6xx.c:262:5: error: no previous prototype for ‘cpu_temp’ [-Werror=missing-prototypes] arch/powerpc/kernel/tau_6xx.c:267:5: error: no previous prototype for ‘tau_interrupts’ [-Werror=missing-prototypes] Compile tested with CONFIG_TAU_INT.
