irqchip/renesas-rzv2h: Add max_tssel to struct rzv2h_hw_info

The number of GPIO interrupts on RZ/G3E for TINT selection is 141 compared
to 86 on RZ/V2H. Rename the macro ICU_PB5_TINT->ICU_RZV2H_TSSEL_MAX_VAL to
hold this difference for RZ/V2H.

Add max_tssel to struct rzv2h_hw_info and replace the hardcoded constants
in the code.
