From: Frieder Schrempf frieder.schrempf@kontron.de

The current implementation in arch/arm/mach-imx/cpu.c uses non-DM code to retrieve the core clock frequency. As the root clock is not listed we currently get:

CPU: Freescale i.MX8MMQ rev1.0 at 0 MHz

Fix this by adding the missing entry, which results in:

CPU: Freescale i.MX8MMQ rev1.0 at 1200 MHz
