[U-Boot] [PATCH 08/13] armv7R: dts: k3: am654: Update mmc nodes for loading sysfw

From: Lokesh Vutla <lokeshvutla@ti.com>

In order to load the sysfw.itb from a mmc device, clocks
should be hard coded to the same value as ROM configured
frequency. Clock updates cannot happen at this point as
sysfw is not yet available. So updating the clock properties
for mmc nodes.
