[U-Boot] [RFC 09/11] armv7R: dts: k3: am654: Update for loading SYSFW from MMC

[Andreas Dannenberg <dannenberg@ti.com>]

From: Lokesh Vutla <lokeshvutla@ti.com>

In order to load the sysfw.itb from an 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.

Furthermore, create a new node for the FS loader framework which we want
to use to load the actual firmware file from the boot media.
