AM65_CPSW_NUSS and its dependencies changed from built-in (=y) to
loadable modules (=m) in linux-next. This breaks NFS boot because the
Ethernet driver is no longer available before the NFS root mount.

Patch 1 adds the CPSW module set to TI_CORE_INITRAMFS_KERNEL_MODULES
for bsp-next so udev can load them during early boot.

Patch 2 adds a standalone initramfs-module-netsetup recipe that waits
for the Ethernet interface to appear after udev loads the modules and
then configures it via DHCP before the nfsrootfs module runs.

Changes in v2:
- Move netsetup from an initramfs-framework bbappend subpackage to a
  standalone initramfs-module-netsetup_1.0.bb recipe (Denys, Ryan)

Moteen Shah (2):
  k3.inc: Add CPSW modules to initramfs for bsp-next NFS boot
  initramfs: Add initramfs-module-netsetup recipe for DHCP network
    configuration
