Subject: [PATCH 5.10 254/663] irqchip/imx: IMX_INTMUX should not default to y, unconditionally

From: Geert Uytterhoeven <geert+renesas@...der.be>

[ Upstream commit a890caeb2ba40ca183969230e204ab144f258357 ]

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

Fixes: 66968d7dfc3f5451 ("irqchip: Add COMPILE_TEST support for IMX_INTMUX")
