[PATCH 04/11] clk: imx: imxrt1050: Remove NOMMU platform support

Fri Jun 19 08:41:01 PDT 2026
From: Frank Li <Frank.Li at nxp.com>
Commercial users and hardware vendors migrated to Zephyr or other RTOS
solutions years ago, leaving the NOMMU platform support effectively
unused and unmaintained.
Remove the obsolete support to reduce maintenance burden and simplify the
i.MX platform code.
