[PATCH 5.10 003/104] gpio: mxs: GPIO_MXS should not default to y unconditionally

[Greg Kroah-Hartman]

From: Geert Uytterhoeven <geert+renesas@xxxxxxxxx>

commit 97c6e28d388a5000d780d2a63c32f422827f5aa3 upstream.

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")
