AM65_CPSW_NUSS and its dependencies changed from built-in to loadable
modules in linux-next. Add them to TI_CORE_INITRAMFS_KERNEL_MODULES so
NFS boot continues to work on K3 platforms with the bsp-next kernel.

Is there any way to link the inclusion of these kernel modules to the
inclusion of the net boot recipe?  If we don't need NFS boot support, how
much larger does this make the initramfs? Just a thought.

I am seeing a size increase of 1MB in the uncompressed .cpio(88MBs -> 
89MB's), I will look into the selective inclusion of the modules once, 
but I do thing it is necessary feature to have since the kernel is 
moving towards making those drivers m and we will need it as a part of 
base package.

Moteen

Understood. At the least, knowing how much this increases the size is
helpful and might be worth putting in the commit message.
