On RZ/G3E, TIEN bit position is at 15 compared to 7 on RZ/V2H. Replace the
macro ICU_TSSR_TIEN(n)->ICU_TSSR_TIEN(n, _field_width) for supporting both
these SoCs.

v5->v6:
 * Retained the macro ICU_TSSR_TIEN by adding _field_width parameter.
v4->v5:
 * Shortened tssr calculation in rzv2h_tint_irq_endisable().
 * Added tssr_shift_factor variable for optimizing the calculation
   in rzv2h_tint_set_type() as the next patch uses the same factor.
v4:
 * New patch

Hi Thomas,

Sending the patch with both commit description and ICU_TSSR_TIEN  macro updated
with _field_width->field_width.

Cheers,
Biju
