[PATCH] pinctrl: renesas: checker: Fix for drive reg field increase

[Geert Uytterhoeven <geert+renesas@xxxxxxxxx>]

With CONFIG_DEBUG_PINCTRL=y:

    r8a774c0_pfc: pin GP_4_3: SH_PFC_PIN_CFG_DRIVE_STRENGTH flag set but not in drive_regs
    r8a774c0_pfc: pin GP_4_4: SH_PFC_PIN_CFG_DRIVE_STRENGTH flag set but not in drive_regs
    ...
    r8a77990_pfc: pin GP_4_3: SH_PFC_PIN_CFG_DRIVE_STRENGTH flag set but not in drive_regs
    r8a77990_pfc: pin GP_4_4: SH_PFC_PIN_CFG_DRIVE_STRENGTH flag set but not in drive_regs

This happens because the checker still uses the old number of fields.

To be folded into commit d5c9688095d29a6c ("pinctrl: renesas: Allow up
to 10 fields for drive_regs") in renesas-pinctrl-for-v5.19.

Ideally, some iterator or index helper should be introduced.
