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.
