pinctrl: samsung: support ExynosAuto GPIO structure
New ExynosAuto series GPIO have a different register structure.
In the existing Exynos series, EINT control register is enumerated after
a specific offset (e.g EXYNOS_GPIO_ECON_OFFSET, EXYNOS_GPIO_EMASK_OFFSET).
However, from ExynosAutov920 SoC, the register that controls EINT belongs
to each GPIO bank, and each GPIO bank has 0x1000 align.
This is a structure to protect the GPIO bank using S2MPU in VM environment,
and will only be applied in ExynosAuto series SoCs.
--------------------------------------------------------------

| 0x10 GPIO_CONPDN | 0x10 GPIO_CONPDN |
| 0x14 GPIO_PUDPDN | 0x14 GPIO_PUDPDN |
|----------------------------| 0x18 EINT_CON (per_bank) |

| ... | 0x20 EINT_FLTCON1 (per_bank) |
| ... | 0x24 EINT_MASK (per_bank) |
| ... | 0x28 EINT_PEND (per_bank) |
