gpio: mb86s7x: share with other SoCs as module 

In order to reuse this driver for the Socionext Synquacer SC2A11 SoC,
which inherited this IP from Fujitsu, remove the ARCH_MB86S7X Kconfig
dependency, and revert the changes that prevent it from being built as
a module.

This reverts commits d65aa4b67b and
d5610e514e.
