Remove the drivers switch related code

We do not need the drivers switch anymore, so remove the
related code in init script of initramfs.

Verification:
- There is not out-of-tree-drivers in the boot cmmandline.
  make sure the ice, iavf and i40e will be loaded with the
  out of tree drivers.
- out-of-tree-drivers is any value, make sure only the
  out of tree driver ice/i40e/iavf will be loaded.

Closes-Bug: 2125028

+Subject: [PATCH] Remove the drivers switch related code
+
+Now that we no longer plan to support switching between different Intel
+eth driver versions or between in-tree and out-of-tree drivers.
+
+This would allow us to skip rebuilding the initramfs if we update these
+drivers, and would put all of the logic to load the drivers and their
+corresponding DDP packages in the rootfs where it's visible at runtime
+rather than being somewhat hidden in the initramfs code.
