Revert "gpio: eic-sprd: Use devm_platform_ioremap_resource()"
This reverts commit 0f5cb8cc27a266c81e6523b436479802e9aafc9e. This commit will cause below warnings, since our EIC controller can support differnt banks on different Spreadtrum SoCs, and each bank has its own base address, we will get invalid resource warning if the bank number is less than SPRD_EIC_MAX_BANK on some Spreadtrum SoCs. So we should not use devm_platform_ioremap_resource() here to remove the warnings.
