[PATCH v7 03/10] PCI: imx6: Rename imx6_* with imx_*

From: Frank Li
Date: Mon Jul 08 2024 - 13:10:27 EST

Since this driver has evolved to support other i.MX SoCs such as i.MX7/8/9,
let's rename the 'imx6' prefix to 'imx' to avoid confusion. But the driver
name is left unchanged to avoid breaking userspace scripts
