Improve UDP speed on PolarFire SoC

Related to #54 Add `clk_ignore_unused` to the `CONFIG_CMDLINE` parameter in `mpfs_cmdline.cfg` and `mpfs_amp_cmdline.cfg` to prevent unused clocks from being disabled. Add `ethtool` and `iperf3` to the `IMAGE_INSTALL` list in `mpfs-dev-cli.bb` to enable network interface configuration and network performance testing. Add `CONFIG_NET_RX_BUSY_POLL=y` to the kernel configuration in `mpfs-linux.bb` to enable busy polling for network receive. Signed-off-by: Vishwanath Martur <[email protected]>
