The vf610 gpio driver is enabled by default for all i.MX machines,
without any option to disable it in a board-specific config file.
Change gpio's Kconfig to allow disabling this driver. Disable it by
default unless we have a vf610 soc. Enable it in the defconfigs
for the i.MX chips that need it.

The vf610 gpio driver is enabled by default for all i.MX machines,
without any option to disable it in a board-specific config file.
Most i.MX chipsets have no hardware for this driver. Change the default
to enable GPIO_VF610 for SOC_VF610 and disable it otherwise.
Add a text description after the bool type, this makes the driver
selectable by make config etc.

The vf610 gpio driver is used in i.MX7ULP chips (Cortex A7, ARMv7-A
architecture). Enable it in imx_v6_v7_defconfig.
(vf610 gpio used to be enabled by default for all i.MX chips. This was
changed recently as most i.MX chips don't need this driver.)

Hi Martin
Please ensure it is compiled when COMPILE_TEST is set. We don't want
to reduce build test coverage.
