The series adds support for icssg_prueth functionality
on u-boot. This series is based on top of master branch.
rproc init needs to be done from uboot command prompt.
The pru/rtu firmware loading is done by prueth driver soon after
config paramters are setup.
A quick update on this series. It seems newer version of this hardware
needs more modifications to this series. Hence please ignore v2.

Currently only slice0/1 of icssg2 instance on am6-evm
is supported. i.e Both slices of icssg2 instance are supported.
Prebuilt firmware can be obtained from AM65 procSDK [1] rootfs at
/lib/firmware/ti-pruss/am65x*.elf

This tests tftp on prueth.
Note: Uboot ethernet driver architecture supports once
instance per probe. So only one of the ports are supported
per instance. So DT of prueth node should have either ethernet-mii0
or ethernet-mii1.
Changes in v2:
It has been a while since v1 was posted. Here are the changes:
* Removed the usage of misc_init_by_ofnode instead used
uclass_get_device_by_ofnode.
* Introduced started variable to keep track of the status of the
prueth device.
* Build Tested on Travis:
