[PATCH] gpio: GPIO_MXS should not default to y, unconditionally

[Geert Uytterhoeven <geert+renesas@xxxxxxxxx>]

Merely enabling CONFIG_COMPILE_TEST should not enable additional code.
To fix this, restrict the automatic enabling of GPIO_MXS to ARCH_MXS,
and ask the user in case of compile-testing.

Fixes: 6876ca311bfca5d7 ("gpio: mxs: add COMPILE_TEST support for GPIO_MXS")
