[PATCH 03/11] ARM: imx: Remove NOMMU platform support

[Frank . Li]

From: Frank Li <Frank.Li@xxxxxxx>

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.
