The variable tssel_n is used for selecting TINT source and titsel_n for setting the interrupt type. The variable titsel_n is wrongly used for enabling the TINT interrupt in rzv2h_tint_set_type(). Fix this issue by using the correct variable tssel_n.
While at it, move the tien variable assignment near to tssr.
