irqchip/renesas-rzg2l: Drop IRQC_IRQ_COUNT macro

Browse Source 
The total number of external interrupts in RZ/G2L and RZ/G3L SoC are
different. The RZ/G3L has 16 external interrupts whereas RZ/G2L has only 8
external interrupts. Add irq_count variable in struct rzg2l_hw_info to
handle these differences and drop the macro IRQC_IRQ_COUNT.
