Subject: [PATCH 1/4] mfd: eiois200: Insert EIO-IS200 core driver to Kconfig

From: Wenkai <advantech.susiteam@...il.com>

This patch adds support for the Advantech EIO-IS200 Embedded
Controller core driver to the Kconfig configuration menu. When
configuring the kernel using tools like menuconfig, you can
select M to build it as a module or select N to exclude it from
being built-in.
