The code is guarded by a condition none of the defconfigs meet (that is
CONFIG_SYS_FAULT_ECHO_LINK_DOWN and CONFIG_LED_STATUS_RED both enabled),
so we can remove the unreachable code sections.

When doing that, there's no caller for miiphy_link anymore, so it can be
removed.

This in turns makes CONFIG_SYS_FAULT_ECHO_LINK_DOWN and
CONFIG_SYS_FAULT_MII_ADDR unused so they are removed as well.

The support found under SYS_FAULT_ECHO_LINK_DOWN requires that the
SYS_FAULT_MII_ADDR symbol also be set. This wasn't previously found in
Kconfig, so add it now.

A few lines of code being guarded by the CONFIG_TFTP_PORT option seems
an unnecessary restriction on the TFTP support provided by a vanilla
U-Boot image. In cases where the TFTP server cannot run as superuser -
and hence cannot run on the well-known port 69 - this quirk incurs a
full reconfiguration and rebuild of the bootloader only in order to
select the appropriate destination port.

Remove the CONFIG_TFTP_PORT option entirely and make the tftpdstp and
tftpsrcp variables always have an effect. Their being unset will mean
that U-Boot behaves the same as if CONFIG_TFTP_PORT was unset. Update
the documentation accordingly. And fix up the single board which was
originally enabling this option.

TFTP transfer size can be used to re-size the TFTP progress bar on
single line based on the server reported file size. Enable it by
default for Renesas hardware to avoid long scrolling walls of '#'
character during long TFTP transfers.

Let net/wget.c and net/lwip/wget.c depend on CONFIG_WGET, and
cmd/wget.c depend on CONFIG_CMD_WGET. This way, the wget code
can be used regardless of whether the wget command is available.

Add support for setting the TFTP block size. The default value (1468)
is fine for Ethernet and allows a better throughput than the TFTP
default (512), if the server supports the blksize option of course.

I tested this change with qemu_arm64_lwip_defconfig. The throughput is
now 875 KiB/s vs. 313 KiB/s before. That is still a low number, but I
think we can't expect more without implementing the windowsize option.

Prepare the introduction of the lwIP (lightweight IP) TCP/IP stack by
adding a new net/lwip/ directory and the NET_LWIP symbol. Network
support is either NO_NET, NET (legacy stack) or NET_LWIP. Subsequent
commits will introduce the lwIP code, re-work the NETDEVICE integration
and port some of the NET commands and features to lwIP.

SPL_NET cannot be enabled when NET_LWIP=y. SPL_NET pulls some symbols
that are part of NET (such as arp_init(), arp_timeout_check(),
arp_receive(), net_arp_wait_packet_ip()). lwIP support in SPL may be
added later.

Similarly, DFU_TFTP and FASTBOOT are not compatible with NET_LWIP
because of dependencies on net_loop(), tftp_timeout_ms,
tftp_timeout_count_max and other NET things. Let's add a dependency on
!NET_LWIP for now.

SANDBOX can select NET_LWIP but doing so will currently disable the eth
dm tests as well as the wget tests which have strong dependencies on the
NET code.

Other adjustments to Kconfig files are made to fix "unmet direct
dependencies detected" for USB_FUNCTION_SDP and CMD_FASTBOOT when
the default networking stack is set to NET_LWIP ("default NET_LWIP"
instead of "default NET" in Kconfig).

The networking stack is now a choice between NO_NET,
NET and NET_LWIP. Therefore '# CONFIG_NET is not set' should be
'CONFIG_NO_NET=y'. Adjust the defconfigs accordingly.
