Add the option to load the bootscript with the tftp command (static IP)
instead of the dhcp command (dynamic IP). For this a new function
tftpb_run similar to dhcp_run, is needed. The selection of which command
to use can be done with the ip_dyn environment variable, which can be
set to yes or no. The ip_dyn variable was chosen as it is already in use
on the imx platforms.
Also edit the bootstd doc.

CVE-2024-42040 describes a possible buffer overflow when calling
bootp_process_vendor() in bootp_handler() since the total length
of the packet is passed to bootp_process_vendor() without being
reduced to len-(offsetof(struct bootp_hdr,bp_vend)+4).

The packet length is also checked against its minimum size to avoid
reading data from struct bootp_hdr outside of the packet length.

There are currently two implementations of dhcp_run(): one in cmd/net.c
for NET and one in net/lwip/dhcp.c for NET_LWIP. There is no
justification for that. Therefore, move the NET version into
net/net-common.c to be used by both stacks, and drop the NET_LWIP
version which by the way does not look totally correct.

It has been over a decade since we had a platform that implemented the
bootp vendor extension support hook. Remove this option due to lack of
use.

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.

dm_eth_phy_connect_interface() is a variant of dm_eth_phy_connect() that
allows to set the used PHY mode, in case the MAC driver needs to fix it
up. The previously static dm_eth_connect_phy_handle() is renamed and
extended for this purpose.

Once the DHCP exchange is complete, if we have an IP address for an NTP
server, set the ntpserverip environment variable accordingly. Although
not necessary to make the sntp command use that server (since it is
known internally to the lwIP stack), this makes the behavior in line
with the legacy NET stack. This is also consistent with exporting the
DNS servers etc.

When both CMD_DHCP and CMD_SNTP are enabled, one would expect the NTP
servers received by DHCP to be used by the sntp command by default. Fix
dhcp_loop() so that it is indeed the case.
