Add a standalone initramfs-module-netsetup recipe that installs
83-netsetup, an initramfs-framework module that configures the network
interface via DHCP before the NFS root mount. The recipe's RDEPENDS
pulls in CPSW and its dependencies, so the kernel modules and DHCP
client are only included when NFS boot support is needed.

Include initramfs-module-netsetup in packagegroup-ti-core-initramfs
gated on :bsp-next, where AM65_CPSW_NUSS became a loadable module.
TI staging kernels (6.6/6.12/6.18) still have CPSW built-in (=y).

Hi everyone, 
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.

Add 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. The CPSW
kernel modules are declared as RDEPENDS:append:bsp-next of the recipe
so they are only pulled in for bsp-next kernels and only when NFS boot
support is needed.

Changes in v3:
- Remove FILESEXTRAPATHS:prepend - redundant in a standalone recipe (Denys)
- Remove PACKAGE_ARCH = "${MACHINE_ARCH}" - script is not machine-specific (Denys)
- Drop k3.inc patch; move CPSW modules into RDEPENDS:append:bsp-next of
  the recipe, linking module inclusion to NFS boot recipe inclusion
- Gate initramfs-module-netsetup on :bsp-next in packagegroup so staging
  kernels (where CPSW is built-in =y) are unaffected

Sorry, I didn't notice this earlier. Is there a reason not to use
busybox-udhcpc which is already included?

This adds two packages:
+dhcpcd aarch64 10.3.0-r0.0
+libudev1 aarch64 1:259.5-r0.arago7.0

And increased the size by 1.6MB on arago-wrynose
 +1,685,504  ti-core-initramfs.cpio
 +327,560  ti-core-initramfs.cpio.xz

Additionally I believe this should have been executed as a oneshot, I.E. no
background service which won't survive the switch-root.
For dhcpcd --oneshot --waitip "${iface}"
For udhcpc -q -i "${iface}"
