irqchip/renesas-rzv2h: Fix wrong variable usage in rzv2h_tint_set_type()

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.
