Subject: [PATCH v2 1/5] pinctrl: renesas: rzg2l: Remove RZG2L_TINT_IRQ_START_INDEX

The RZ/V2H(P) has 16 IRQ interrupts, while every other platforms
has 8, and this affects the start index of TINT interrupts
(1 + 16 = 17, rather than 1 + 8 = 9).
Macro RZG2L_TINT_IRQ_START_INDEX cannot work anymore, replace
it with a new member within struct rzg2l_hwcfg.
