thermal: debugfs: Use seq_puts() for constant string output

Replace seq_printf() with seq_puts() when outputting a constant string
without format specifiers in the thermal mitigation debugfs interface.

seq_puts() is more appropriate and efficient as it avoids unnecessary
format string parsing overhead.

No functional change.
