Revert "gpio: eic-sprd: Use devm_platform_ioremap_resource()"

This reverts commit 0f5cb8cc27.

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.
